Me and my girlfriend stayed at Michela's place and I must say that we were delighted and had a wonderful experience. Room was same as it was on pictures on Airbnb site, so you literally get what you see. Bed was big, room was warm and bathroom was cozy. Fridge was filled with water and juices once a day, we were getting coffee and tea so it was more than we expected.
Michela welcomed us in well manners, showed us a room and whenever we needed some information or anything else she was willing to help us and responded to our messages really fast so we didn't have anything to worry about.
As for location, it is outstanding, well connected via metro, and in Rome it can get you anywhere; it was easy to reach from airport or central station, which made it easier for us to find the place. We liked to walk around instead of using public transport so I also must add that the location is perfect ànd well connected to other parts of town (such as Trastavere or monuments) and everything is within half an hour by foot.
I would honestly recommend Michela's place to everyone and will definitely go again once I visit Rome again.
