We stayed for 5 nights in the Marco appartment and it was very restful.
The appartment is located in a quite area. The closest metro station (15 minutes long by walk) is a main one with plenty departures by train, bus and metro. There is a direct line to the airport from this metro station. This is also the end line of a bus line traveling all around in Rome ...very convenient when we were far from a metro station, traveling around. We took the bus ending directly at this station and the return trip was without any surprise.

The appartment is clean, brand new and wonderful as described in the ad. It is located close to a supermarket open on sunday and late in the evening. Some restaurants and bakeries are on the main street of the appartment.
Marco was very kind and "pro" with us, giving us some tipps for the visit of the main places.
He proposed us some very convenient services such as the transfer from and/or to the airport .... no stress at all during the travel as we were dropped directly at the right place from the airport ...
We would recommend the appart for a stay in Rome.
