Emanuele was an excellent host! He welcomed us at the metro station Porta Furba and walked us to the apartment. We spoke in Italian but he's fluent at least in French and in English. He directly gave us a map of Rome and took the time to show us the must-sees and explained us how to reach them. He also adviced us restaurants he likes and they were excellent! We've seen him almost every days but he was neither intrusive nor distant : he just was very respectful and helpful.
The apartment is very well situated even if it's not in the old, "pretty" center. There's a metro station (Porta Furba) practically in front of the door so you can reach the center very easily and rather quickly. There's also a excellent restaurant at the corner, "da Baffo", which cooks excellent meat and where actual romans go!
The room and bathroom were perfectly clean and spacious. The airconditioning was very appreciated at night after a full day of roman sun exposure! The only little negative point for the light sleepers is the noise in the streets which seems to never stop! But that's a small detail...
Also, don't be afraid when Emanuele will ask you the "stay tax" ("contributo di soggiorno") of 2 euros/night : it's not a scam but just an absurd roman law... For more info : http://www.turismoroma.it/news/prima-news-in-evidenza
We had an excellent stay at Emanuele BNB!
