The ‘floatel’ is the brainchild of artist Mikael Genburg, known for his unique hotel experiences including one in a tree in a city centre park, and 'Ooops', the sunken villa which opened this summer not far from Utter Inn by Lake Malaren, Vasteras. Utter Inn has an above-surface kitchen inside a little hut made to look like a traditional Swedish cottage. At bedtime guests climb down the hatch to their sleeping quarters which has an all-round view of life under the surface.
