If you are looking for a place to have a nice base while you explore Rome and the amazing neighbourhood of Trastevere, the Domus Trast is a good choice.
The location is definitely the biggest plus of the apartment. Right in the middle of Trastevere with nice restaurants, bars and cute little streets as well as in walking distance of bigger tourist attractions like the Coloseum and Trevi Fountain.
The apartment is very small (the photos posted by Paola are very accurate) and equipped with the basic necessities. Nothing luxury, but it matches the price. We were a little surprised about how loud the noises from the buildings front door was, but we used earplugs at night and were not crazy bothered by it.
All in all a good experience and just what we booked it to be!
