Lisbon rises in tiers over its hills above the Tagus estuary, facing the Atlantic. Winters here are mild but often rainy and windy, and the water in outdoor pools cools quickly from October to April. I've picked hotels with indoor pools, gardens hidden in the heart of the city and rentals with a private heated pool. I've selected 28 places, all rated at least 8/10; the top-rated is Lx Villa 10m to downtown, heatable pool (4.95/5).
Each city has its own selection, with a page for each type of accommodation.
Places are ranked from highest to lowest rated. The yellow bubble shows the advertised water temperature, when it's known.
