Before I get to the good stuff, I would suggest that if you have mobility issues, the Relais is not for you. There is a stairway you must climb to reach the elevator.
If climbing stairs is not an issue, the Relais is a great place to stay while in Florence. The owners and staff are very friendly and speak English. The atmosphere is very relaxed and informal. The building is old, dating I think, from the 14th century. Therefore, it's not a sleek, modern facility. But it is very interesting! Staying in a room with very high ceilings was unique. The bathroom was very modern and clean.
The Relais is in a great location too. It is easy walking distance from the railroad station. We used the high speed trains for day trips, including one to Venice. It is also very close to the city center with the various museums, squares, bridges over the Arno, etc.
We definitely would stay there again if in Florence.
