We stayed 4 nights in Rome at Marco's apartment. The place is very close to Termini station (about 10 min walk) and Vittorio Emanuele metro station (3 min walk). Furthermore restaurants and supermarkets are within walking distance.
The apartment is located in a nice building, it is completely renovated and very spacious (2 bathrooms). All amenities are provided and I must say that we felt like home during our stay. Finally the interaction with the host was very good. Overall a great experience. Highly recommended! Thanks a lot Marco!
