We had a wonderful time staying at Paola's place.
The place is really nice. Nicely decorated, high quality appliance and furnitures, the beds are very comfortable. Even though it's inside an old building, it has great modern rustic chic style. It had everything we needed, and the whole place was very clean (well worth the mid term cleaning fee).
The location was also great. Very close to the central market and Duomo, yet hidden in a non touristy street. It's the perfect balance for us to have easy access to attraction vs feeling local.
Paola has been very accommodating and very responsive since I made the reservation. Amalia the cleaning lady was super nice too.
On general I feel very happy that we chose this place and would recommend to anyone (who doesn't mind some stairs).
