Two of us stayed here for one week. I'd like to list the pros and cons.
PROS:
We were met by Riccardo who is charming and very helpful. The neighborhood is great. You are literally steps from the Ponte Vecchio and the Pitti Palace in a neighborhood teeming with life. There's a wonderful supermarket within steps of the entrance to the building and numerous small shops and a few restaurants in the neighborhood.
The elevator and the building are excellent and the apartment has soundproof windows and adequate space for two people; the bedroom, kitchen and living room are more than adequate. The washer and washing machine work just fine but, remember this is a Italy, and you can expect to use a folding rack to dry your clothes.
CONS:
There is not one comfortable chair in the entire place. We had to take pillows from the couch in order to sit at the kitchen table. Speaking of the couch, it's a disaster. It's a 20 year old sleeper couch and we were warned not to use it because it's so uncomfortable. In addition the shower is almost dangerously small and difficult to use. Garbage is a problem as there are no garbage disposals, one must accumulate unused food along with other garbage. We bought large bags and stored garbage in the apartment because there's no place else to put it; it builds up pretty fast over a week.
Bottom line; if this place was in a less interesting neighborhood, we would not have been happy.
