I found this Arumu Uffizi on Orbitz and wanted to try a local hotel. It was "different" and that's the best way to describe it. I booked a triple room thinking it the 2 of us would have room to relax. Nope, it was an uncomfortable twin bed and a full size bed. There weren't toiletries to wash my hair. Just as well because there is only enough hot water for two people. The hotel was really basic, small in every way. There is no curtain or door on the shower, which was 7
