I stayed at Marco's with my parents and son for the week, it was perfect. We had plenty of space and everything was crystal clean. Plus, the location was unbeatable. It's very close to the Colosseum (and some of the more touristy restaurants), but there are also several local spots within a few minutes' walk for a more authentic taste of Rome. Marco promptly helped us with anything we needed during the week and arranged transportation to and from the airport, which was a huge help for my travel-anxiety parents. Cannot recommend enough.
