Maurizio's place is simple but spacious - there was plenty of space for us and our four kids, and it is also set up well for two families to stay together. Everything was clean and in good working order. The apartment has good curtains to keep the rooms dark until you are ready to get up. Maurizio was a very welcoming and helpful host - he provided a number of recommendations for great restaurants as well as interesting places to visit besides the globally-known Rome landmarks.
The location of the apartment is very convenient. It is very easy to get to - we took the direct train from the airport to the main train station (Roma Termini) and just walked to the apartment from there. There is a metro station less than a five-minute walk from the apartment, and from there you can easily get to most of the famous tourist destinations. The neighborhood around the apartment has good restaurants and some local attractions as well.
The main caveat I would note is that the apartment is located on a major streetcar line. They don't run all night, but start pretty early in the morning. If you are a sensitive sleeper, the noise might be an issue, but it didn't really bother us. As some other reviewers have noted, there were some issues with the WiFi as well. It worked great in the common area, but in the bedrooms our devices would get disconnected every couple of minutes. Again, this wasn't a major issue for us but could be an inconvenience for some.
Overall we really enjoyed our stay and would definitely choose Maurizio's place again!
