Marys was very helpful and friendly with us. The room was small but enough for us: table, shower, tv, wifi and queen bed. There is a kitchen with breakfast included.
The apartment is close to a metro station (just 5 minutes walking and just two stops from Roma central station) and a Tram stop or bus stop, altough we were walking from the apartment to Coliseo and to the city center.
For sure I'm going to come back to the same place :)
