Barbara is a great host. We arrived late but she waited for us in front of the Apartment and explained everything to us and left some maps to navigate around.

Location:
The Location might look like a Little bit outside. But it is very convenient.
There is a bus Station where u can take bus 928 to the door of vatican directly. Piazza Mancini, which is end Station of tram nr. 2, you can take other buses (like 32) to go around. Tram 2 takes to right to Flaminio from there you could walk to spanish steps in 15 min.

Apartment:

The Apartment is very clean with two bedrooms. We are four and found enough place. The Couch in Lounge could be used as another bed. We cooked coffee which was provided by Barbara. The bathroom is clean and fully equipped. Barbara provided enough clean towels for us 4. The kitchen is small but you find all the Basic things.
The house itsself used to be olympic village for athlets. There are many parkspaces in front.

In summary I would recommend this Apartment to everyone.
