We were welcomed very warmly by Adriana (and her kids). She started by giving us a tour of the nice flat, explaining and showing us everything we should know for our stay. Then, she gave us a lot of advices about what we could visit in Roma with many details, including restaurants with her personal favorites that are all written in a notebook. The apartment is very well located: around 15min walk from the coliseum, the forum, the palatin hill, the circus maximus and the caracalla baths just to name a few. There is also a subway station (Circo Massimo) in the way if you need to take the public transport. The flat surroundings are very quiet, you can even hear the song of the cicadas when you go out!
Overall, we had a great experience during our 3 days stay there but it wasn't enough to visit everything we wanted, so we'll definitely come back another time to the same place and continue our Roma tour where we left it :).
