We stayed 5 nights at Stefania's place and just loved it!
The house is not right in the city center but it is very easy to get there walking.
We ended by using the buses and the subway because we had our 4 months old baby and it was very easy as well.
The house was very clean and it corresponds exactly to the pictures.
If ever you are searching for a place to stay, you should decide to stay at Stefania's!
