We had a good time in Rome staying at Andrea's apartment. It is located in a quiet residential neighborhood and the walk to the metro station is not too difficult (about 10-15 minutes). There is not a lot of groceries,cafes and restaurants in this area but we found one steak house down the street and were very happy with our meal. The apartment itself is fine. We stayed during a heat wave and suffered a bit from the heat (there are nice ceiling fans but no A/C). As mentioned by other guests, the shower is basic and quite small. The kitchen doesn't have any special equipment, coffee, tea, etc. but it is functional if you want to load up the fridge and cook some meals.
Andrea was a great host, very responsive and provided a nice guide to Rome ahead of our visit.
