Yes, that’s right, you sleep underwater! Utter Inn is an art project by Mikael Genberg – a local artist and sculptor which offers an underwater accommodation for the public. This floating underwater hotel in Stockholm, Sweden is sets 1km out to the middle of a Lake Malaren. It lies 3m below the surface of Lake Malaren and contains only twin beds and a table.

Guests can also swim, sunbathe or watch the fish (from both upstairs and downstairs) at the hotel. It’s a remarkable feeling to go to bed while the fish surround and watch you carefully. If guests prefer deluxe accommodation, someone can deliver dinner by boat in the evening. Average Cost: $250-350
