We stayed here in July of 2012 - in a quadruple room with our 2 kids. The hotel is super clean - and the room was very big for European standards. The room came with a king size bed and 2 twin beds that folded out from the sofa chairs. My only complaint about the hotel is that the kids found their beds very lumpy and uncomfortable. They complained about them every night!
However - the staff at the hotel were all wonderful - especially Frederico at the breakfast buffet! The breakfast was very good - and the front desk staff were all very helpful - with tips for restaurants, etc.
Florence is a wonderful city - and the hotel was ideally located. It was about 3 blocks from the Duomo - and 2 blocks from the outdoor market. It was close enough to the heart of the action - but still far enough away that you felt like a local! Hotel is also very close to the Accademia. It's about 7 or 8 blocks from the train station.
