Christina was a lovely and kind host.
She gave us warm welcome and even waited for us until late night and at that late hour, explained us where to find what and where to visit. she also let us leave the luggage in the room and lock it after the check-out because the next guest were supposed to come at midnight.
the room was not a luxurious at all but it had everything we need for the stay. bed, bathroom, kitchen, wifi. yes the room provides you the everything you need but not everything is in perfect condition.
the location was great. 3 minutes to Metro A which can take you to city center and Vatican in about 10~20 mins. and you can find a super market and a nice park just around the corner. and there are cheap but good local coffee shops near the apartment, where the local residents come to have their breakfast.
now, some bad sides. the room wasn't very quiet. we stayed there for 4 nights. the first 3 nights were fine. the guy sleeping in the living room (there's a bed and a chair behind the curtain in the living room right beside the room door) was very quiet but the 4th night, there were 2 guys sleeping in the living room and they talked a lot and we could hear everything they say. (we didn't understand the language so it was even more irritating)
and Wifi is extremely slow and the you might have a hard time even connecting to it.
the boiler got out of order at the last night of our stay. before then, it was perfect but somehow it just didn't work. hope they have fixed it already.
