Flavia's flat was very comfortable. Everything looked new and the decor of the place was spot on with nice touches to remind us that we were in Florence. The mezzanine level is a cozy nook to chill out if you need some time alone.
The apartment had two bathrooms ( with toilets) which we really appreciated. The kitchen had the basic utensils. The location of the apartment is spectacular. Walking distance from everything while being away from the crowds. It was also easy to get a cab via the mobile app that everyone uses in Florence.
The apartment is on the fourth floor and there is no lift so I got a good workout carrying up our suitcases. But we knew that before hand and it wasn't a big deal.
We spent five nights and overall it was a very enjoyable stay.
