We were very satisfied with our stay, had everything we needed and were happy to have an air conditioner at the temperatures in Rome! Also my communication with Chiara was very easy, friendly and welcoming. I didn't actually meet her though, but Julio who let us in was very nice and friendly, informed us about everything and we didn't have to wait at all.
It's good to know though that the apartment is really small (the mirrors make it look a lot bigger) and there are glass fronts in the walls of the privat room (if you are two couples there is very little privacy since you can see each other). Apart from that it is very nice and well situated in Trastevere.
