We stayed a week and we were 3 adults.
The apartment is functionnal and very well located. Great restaurants around, amazing gelato. The host is very nice.
However, is it very loud because of the neighbours, so it's difficult to sleep in the living room.
There were only 4 functionnal outlets which was a bit complicated to manage - especially if you have a computer, phones or a camera. It was not possible to charge our electronical devices in the bedroom, which was a bit annoying.
