The location was great, right across from Pitti Palace and walkable to all the sites on the other side of the river via Ponte Vecchio. However, we had many problems. First, our keys were not left for us to get into our rooms and there was no on-site staff to help us. This took over an hour and a half for the phone agent to resolve by getting someone to come and help. We noticed another couple had the same problem a day or so later.
Our room was attractive, clean, large, and the bed was fine. However the air conditioner did not work and there was no hot water for our showers. These problems were not resolved during our stay. We never saw anyone in the office, only the cleaner who could not help. Our friends' room was less attractive but did not have these problems.
We did have our own bathrooms, which was not clear on the listing whether they were ensuite. I tried a couple times before we arrived to confirm this, both via hotels.com and directly with their email but never received a response, we just had to cross our fingers we would not have a shared bath.
