I would highly recommend Stefania's place. It's super cute like a little doll house that an Italian Grandma owns and is such a good location. Only a 20 minute walk from the train station and so near to everything else.
The apartment was clean and a lovely area on a quiet street but minutes away from restaurants and bars so you never had to walk far if you didn't want to.
The only down side was that the shower wasn't hot, it only lasted for a few minutes and then went cold and the apartment wasn't super warm and they weren't able to sort the temperature of the shower out whilst we were there but I wouldn't let this put you off as it really was a great place to stay, you just can't have long showers. Other then this I would highly recommend this lovely apartment!
