Appartment is very nice and proper, big rooms, two nice bathrooms, good airconditioning, everything is present and available. Nice view from balcony at streetside. Small shops and supermarkets all around.
Only thing to be aware of: It is situated in a part of the city a bit further from the touristic part(s). So it takes about 20 minutes by bus to Vatican City, or to Teatro Marcello/Piazza Venezia. But several busstops very close to the appartment, so with a little patience the possibilities to travel are plenty. (No metro station nearby)
Besides, being part of the daily living in a normal residential area of Rome has definately its charms.
Communication with owner is smooth and good, no suprises or whatsoever.
I can recommend this appartment if you want to discover Rome without being in the very crowded touristic areas constantly. At least we had a great stay here, with two pretty critical teenage daughters who didn't complain at all (even Wifi is very good :-) ).
