Da Nang vs Koh Tao vs Lisbon: three nomad bases compared on cost, visas and internet

In the Da Nang vs Koh Tao vs Lisbon choice, Da Nang is the cheapest base and has the fastest home fibre for the money, Lisbon has the best infrastructure and the only real residence route for remote workers, and Koh Tao sits between them on rent but last on internet and hospital access. Your passport and your client time zone decide the rest.

Linda and Etienne met in a coworking space on Koh Tao in early 2026, and Linda is now based in Lisbon. Every figure below comes from a public source checked in September 2026.

Sources for every line are in the sections below. Nomads.com cost figures are crowd estimates read on 26 September 2026; use them to rank the three, not to budget. To weigh them against your own priorities, run the destination comparison tool.

Is Da Nang cheaper than Lisbon and Koh Tao for rent?

Yes: Da Nang is the cheapest of the three by a wide margin, and Lisbon costs roughly three times as much. A typical Lisbon T1 rents for EUR 1,250 to 1,450 a month in 2026, with an average near EUR 1,350 (Investropa).

On Koh Tao, rooms go for 8,000 to 10,000 THB a month, apartments for 15,000 to 18,000 THB, and beachside places start at about 20,000 THB (Digital Nomads World).

In Da Nang, a one-bedroom near the beach costs 10 to 13.75 million VND (USD 400 to 550) and an inland studio 6.25 to 8.75 million VND (USD 250 to 350) (HitchHive). Leases start at three months with one month's deposit, and a six to twelve month lease is typically USD 50 to 100 a month cheaper than a three-month one (Da Nang Visa Run). One trap: landlords bill electricity at 3,500 to 4,000 VND per kWh, which adds USD 32 to 60 a month depending on air conditioning (HitchHive).

Which base has the best internet for remote work?

Lisbon has the best internet, Da Nang the best value, and Koh Tao the weakest connection. Nomads.com lists average speeds of 100 Mbps in Lisbon and 18 Mbps on Ko Tao (Nomads.com Lisbon; Nomads.com Ko Tao), both read on 26 September 2026.

In Lisbon, internet-only fibre at 500 Mbps to 1 Gbps costs roughly EUR 27 to 30 a month (GrowIN Portugal). Desks cost more: plans start at EUR 99 a month at Heden and reach EUR 325 plus VAT for a resident desk at Second Home (Heden; Second Home).

On Koh Tao the coworking space is the connection. Blacktip advertises two fibre lines, a 5G backup with automatic failover and a generator that powers the whole office (Blacktip). A month at Tao Hub has been reported at 5,000 THB or less (Digital Nomads World).

In Da Nang, home fibre starts from 190,000 VND a month with VNPT and a technician usually comes within one to three days (VietnamSpot). Coworking runs from 1.8 million VND at Circo to 4.5 million VND at HIVE, with Seaview at 2 million VND and open 24/7 to members (The Digital Nomad Asia). Cafe wifi is uneven on upload, which is what a video call needs: one cafe tested at 173 Mbps down but 9 Mbps up, another at 138 down and 1 up (Two Packs and a Pup). Nomads.com shows 7 Mbps on average for Da Nang (Nomads.com Da Nang).

Which country makes a long stay easiest?

Portugal is the only one of the three with a residence visa built for remote workers, and Vietnam has none.

1. Portugal. EU citizens live there by right of free movement. Other passports get 90 days in any 180 under Schengen rules, or apply for the D8. The official test is an average monthly income over the last three months of at least four times the minimum wage (Vistos MNE), which is EUR 3,680 a month in 2026; the process from application to residence card takes six to nine months (Global Citizen Solutions).
2. Thailand. Since 15 September 2026, 60 nationalities, including France, Germany, the UK, the US and Australia, enter visa free for 30 days, replacing the 60-day exemption (TAT Newsroom). One extension of up to 30 days is possible at immigration (Royal Thai Embassy London). For a real base, the Destination Thailand Visa lasts five years, allows 180 days per entry plus one 180-day extension, and asks for 500,000 THB in funds; the London embassy charges GBP 300 (Royal Thai Embassy London).
3. Vietnam. Every nationality can get a 90-day e-visa (Vietnam National Authority of Tourism) at USD 25 for single entry or USD 50 for multiple entry, processed in three working days (official e-visa portal). Twelve countries, including France, Germany and the UK, get 45 days visa free for any purpose until 14 March 2028 (Embassy of Vietnam in Japan); twelve more, including the Netherlands and Switzerland, get 45 days for tourism only until 14 August 2028 (Embassy of Vietnam in Japan). Americans and Australians are on neither list. Vietnam has no digital nomad visa (ExpatDen), and since 15 December 2025 an overstay of 16 days or more can lead to deportation (Viet Nam News).

Where is healthcare easiest to reach?

Lisbon and Da Nang both have serious hospitals in the city; Koh Tao does not. The Koh Tao government hospital runs a 24-hour emergency service, and a private clinic partnered with a Bangkok hyperbaric centre treats diving cases (Koh Tao Complete Guide). Anything beyond that means a speedboat or ferry to Koh Samui at 2,000 to 8,000 THB, one to two hours depending on the sea (Baanlyy).

In Da Nang, Vinmec is JCI accredited and open 24 hours (Medical Tourism Co). A GP visit at Family Medical Practice costs 2.2 to 2.8 million VND (USD 86 to 110), and critical cases are flown to Ho Chi Minh City or Bangkok (Based Da Nang). Lisbon has public SNS hospitals and private hospitals inside the city.

Which months should you avoid in each place?

Da Nang has the harshest bad season, Lisbon the mildest. Lisbon sees rain on about 10 days a month from November to January, and the sea peaks at about 20.5 C in August and September (Climates to Travel). Koh Tao's monsoon runs October to November, when dive visibility drops from 20 to 30 metres to 5 to 20 (Wonderland Koh Tao). Da Nang's rainy season runs September to November, with about 620 mm in October and 380 mm in November (Da Nang Hotel Guide); from 26 to 29 October 2025, water reached 1 to 2.5 metres in several Da Nang wards (VietNamNet).

Which is the best digital nomad base in 2026 for a European client schedule?

Lisbon suits it best, because it shares the working day with most of Europe. Thailand and Vietnam both run on UTC+7 all year, which puts them six hours ahead of Lisbon in summer and seven in winter. A 10:00 Paris standup in summer lands at 15:00 in Da Nang or on Koh Tao, and a 17:00 Berlin call at 22:00.

In one line: Da Nang for cost, Lisbon for infrastructure and legal certainty, Koh Tao for the sea. Next, read our guide to becoming a digital nomad and the internet guide.
