We had a nice stay at this place!
The location is very nice: walking distance from Trastevere and good bus-connections to wherever you want to be in Rome, nice coffee place next-door and shops and restaurants nearby.

The rooms are spacious and well-equiped. The apartment is in a well-maintained and safe building. The host Maria is very nice. Note that these are rooms in a shared apartment, but it worked very well for us. The living room is nice to eat in and you even have a small balcony.
The water-pressure in the shower isn't great, but I guess that's often the case in Rome.

We would recommend staying here!
