I stayed here with my family (2 adults and 2 teenagers). The location is fantastic. It's a 2 minutes walk to the metro station and about 15 minutes to St Peters. There's a small supermarket around the corner as well as a nice bar for breakfast.
The apartment was very clean and large enough for the family.
Valentina is a great host. She was in contact prior to our visit to give us all the information we needed, and responded quickly to any questions we had. We had a problem on the day we were checking out with our car rental company, and Valentina couldn't have been more understanding as she allowed us a very late checkout, which made a very stressful day much less so.
