Maria's place was fantastic and just what was needed for my stay in Rome. It was in a really nice neighbourhood and was quiet. It was fairly close to the metro and had a shop for food and drinks just down the street. They offered a lift to and from the airport for a cheaper fare than taxis but I chose to just use the public transport as it was easy.
The one issue that should be noted is he place did not have working air conditioning and there wasn't a fan available at all. This made sleeping during the summer heat fairly uncomfortable. If this was improved then I would have been extremely happy with the experience. Overall fairly good.
Thanks guys!
