Roberto met us at the apartment. He was really friendly and helpful. He was fluent in English which was great as the limits of our italian is "ciao" and "grazie." He also arranged a taxi for our return early morning flight. He offered us some underground tours at reasonable prices which sounded awesome but we were unable to take any. The room is really cute, it is small but functional. The shower has good water pressure although it seems to run out of hot water after about 10 minutes so the second person may need to wait a while before theirs. Bed was comfortable and everything was clean. We didn't use the kitchen although it has a really cute, ornate sink. Air conditioning is quiet and very useful for summer nights. A perfect base for exploring Rome.
It is beside the A line which makes it very easy to get around to the tourist spots. The Re Di Roma stop is at the park in the middle of the roundabout. It is just out of the very centre and felt like a more authentic Roman experience. The food places around the apartment are cheap and have great food. People in the area are very friendly and helpful. They will offer assistance and are patient in helping explain things to you. Just make sure to make an effort to speak some Italian and don't just assume they are able to speak English. Overall a nice place to stay in a nice location, highly recommended! :)
