The seven day stay at Alessandro's listing in Rome was generally pleasant. Alessandro was very easy to communicate with in English, very prompt in responses and gave good advice about the area. The listing's location is very convenient for seeing the historic sites in Rome, and I would recommend it as a good base to see all the sites assuming one can walk comfortably 10-20 minutes (no elevator in the building, and Rome is not a very handicapped-accessible city anyway).
The good: the kitchen had everything it needed for basic cooking, the shower always had hot water, and the bed was comfortable. There are lots of restaurants, a few city supermarkets, a subway station, and a couple coin-laundry shops within 5-10 minutes walk.
The bad: the apartment is not large, but the wifi only worked well in the kitchen/living room area, not in the bedroom. Not really a big problem, but some people may wish to use wifi in the bedroom and may not be able to do so. It is also important to note that the apartment does not have air conditioning, which is probably not normally a problem, but there was a historic heatwave during my week-long stay in Rome, and the apartment was hot. Windows can be opened for air flow, but like most older buildings in Rome, there are no screens in the windows to keep insects out. The first few days were fine, but by day 4 or 5, there were mosquitos in the apartment. The couch and chairs in the living room were OK, if a bit old, and the small fan provided struggled to keep fresh air coming in. Generally speaking, I was satisfied with the stay and it is a very good value considering how expensive accommodation in this area can be.
