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

We had a wonderful time! The Bernini Palace exceeded all our expectations. Exceptional sevice! The staff was welcoming and accommodating right from the moment we checked in. The Bernini Palace a prefect blend of luxury and comfort. The breakfast was so delicious with a wide variety of options to choose from. We will certainly return during our next visit to Florence.
