My family and I arrived in rome on april 26 and left on may 2. everything was okay. Roberto was very nice and he was very easy to talk to. He explained everything pretty well and had an emergency phone for us to call him (though we never used it because everything was fine). The unit is clean and there are bus stops near by. Although it is not very close to the center, it was very close to Vatican City (a few minutes walk) and had a metro station a block away which in 2-3 stops will take you to the trevi fountain, the spanish steps, etc. Though travellers with plenty of luggage might have difficulty because the metro stop near the place had no escalators.

The place had almost everything from a good working kitchen with enough plates, utensils, pans to the fridge and freezer. Oh and the place had two bedrooms and was pretty spacious.
Overall, our stay was pleasant and Roberto checked in on us every now and then.
