Meri-Karina, Turku, Finland

This lovely spot in Turku is right on the sea, so you can take a dip from the pier whenever you like!

There's also an indoor pool if you don't fancy a cold plunge, and a sauna too of course. Rooms are clean, bright and functional, and there's a gym too.

There's a shared kitchen here as they don't serve meals on site. You'll probably want a car here to make the most of your surroundings - there's free parking on site - although there is an hourly bus to Turku city centre.
