What I liked: The apartment as a whole is lovely, and the location is perfect for exploring central Rome on foot. The room overlooks a courtyard and is very quiet. I greatly enjoyed meeting and talking with the other guests. Massimo and Coca are delightful and made me feel very welcome, eager to help in any way they could. The kitchen has plenty of pots/pans/dishes/etc., and the air conditioning (shared by my room and the one next to it) works well. The terrace is a pleasant place to sit. The wifi worked well.
What wasn't so great: The small tables and lamps that appear in the photos were not in the room while I was there; I had to use a chair as my bedside table, and the only lighting was an overhead hanging lamp in each of the rooms. The bed was a bit too hard for my taste (although Europeans will probably like it). My bathroom was very small, and I had to squeeze around the door to use anything but the sink. Although there is a large refrigerator in the kitchen (which is on the upper floor), it was off limits to guests, who had to share a small one on the lower floor.
