Overall, our stay was good. As others say in the review, you can't beat this location. It's in one of my favourite squares in Florence and is close to everything you'd want to see or do on a short stay.
However, the place itself could do with a bit of work. The shower curtains and blankets need to be cleaned/replaced. The shower itself needs to be fixed. The WiFi is terrible and you can't get mobile signal on the building.
It was stressed to us not to be late to check in. However, we were on time and the representative sent to check us in was not! On top of that, he was unprepared and didn't know how to open the door or where to find the keys, making it a very unprofessional encounter. All of these small things could be addressed to make this a wonderful place to stay. Until then, it's merely passable.
