Good communication and response: getting there, checking in and out was fast and easy.
Good location: not in the heart of downtown but in a nice neighborhood (San Giovanni) away from tourist crowds and close to a metro station.
Premises: the apartment is on a third floor and there is no elevator, so be prepared to climb some stairs. Comfortable bed, tiny bathroom but good shower. Complete kitchen, excellent WIFI connection and cable TV.
Overall we would highly recommend this place.
