Alessandro and Vanessa are really good hosts. We spend 5 days at their place with my wife and my 1 year old daughter and i could say that we were really demanding guests but they answered all our questions immediately. We faced some problems during our stay but they were just there to solve it.
Things positive about the place:
* A few steps to Spanish Steps. 10 minute walk to many of the attractions. Is a good place to reduce transport/metro costs. Also there are many supermarkets and good restaurants around
* During our visit it was chill in the nights and the place has two air conditioner which are working properly. It was really warm inside
Things to pay attention:
* Inside of the appertment is newly renovated and very clean. But the building is an old one. (this is usual for Rome, most of the buildings are old) So that the infrastructure is not good enough. The fuse blown a few times. You should pay attention not to put too many load to the plugins.
* If you are obsessed about the sounds when you are just to fell asleep, the air conditioner works a little bit noisy.
