We stayed here during our recent trip to Florence. This place is a true gem - short 10 minute walk from the train station. Reception staff is incredibly accommodating and very helpful, rooms are beautiful and very quiet and you just cant beat the location. Literally right by the Ponte Vecchio in the middle of everything!
As soon as we arrived we were greeted by the reception staff, they took care of our luggage and gave us tour of the place. It was built in 13th century and owned by the same family until 18th century and was later converted into a hotel. Roof top terrace is beautiful - incredible views of Arno river, Duomo and you can watch sunset from there. They have full service roof top bar, which is also equipped with an awesome coffee machine - and run on "honesty system" meaning you make your own drink and just fill out little piece of paper letting them know what you had so it can be charged to your room upon checkout.
Breakfast buffet was also great and had alot of options. This place has solid complimentary wifi - which was important to us, so we could face time with our kids.
I saw comment on no shower - we had regular room, it was a bit small, but super cute and full of character and we did have a shower (no bath tub).
They even let us leave our luggage there in depository for 2 days while we went to Cinque Terre, so we didnt have to bring all our bags with us, which would have been quite a hassle.
All in all - great property I would highly recommend.
