David's appartement was very well located to get to/from the airport as well as to get to the city center. You can walk to the main attractions and visit other lest touristy places on the way or take the subway and be in the Colisseo in 10 minutes.
The room and the appartement we really comfortable and David and Caterina are super hosts, we felt really at home! They bring out the nice part of Airbnb, to get to know people that live in Rome and not just the city, the monuments, etc.
