We stayed here for 9 days. Marta was super friendly and helpful when we arrived and offered extra help if needed throughout our stay. The apartment was on the second floor and was in a perfect location. Very close to a lively area with lots of restaurants and shops but was a few blocks away from the noise for quite nights. And within walking distance to most tourist sights. Perfect for us.
The apartment slept 5 perfectly and 6 would have been no problem. The pull out bed is comfortable and I slept well there. The apartment is full of windows and lots of natural light.
The internet was very slow at times but that would be the only problem we had.
I would recommend staying here for your trip to Rome.
