10/10 would recommend! The apartment is very lovely and so is Roberto. We had everything we needed in the apartment and it was very clean. The location is great because the train to the airport is only a couple of minutes away and you can walk to all the big sightseeing areas in about 30 minutes. I would recommend having breakfast at Caffé Number One which is just a short walk away from the apartment. The ladies there are really nice and the Panino is to die for (also coffee is only 1,20€). For dinner in Trastevere i would recommend going to the beginning of the street than go into one of the little side streets and you will find many great restaurants (eg Taverna 51, Pasta e Vino,…). The neighbourhood is quite loud but so is Rome in general (you get used to it pretty quickly, i promise).
