We enjoyed our stay in Daniels apartment. First, we haven't had enough towels, but both, Daniel and Alicia reacted promptly when we contacted them. And Daniel helped us the same day, when one of the showers needed repairing. The apartment is perfectly located in Garbatella, from there you have direct access to the subway systems which brings you to all the important places in Rome. The bus to Trastevere is only 200 m to walk.
We think it would be good to limit the amount of guests to 12, since one room was extremely crowded (we were 16 and 8 people lived in one room) and there are only two bathrooms. But, altogether, it is a good place for groups of young people. We found everything we needed in the kitchen and had a good time.
