Antonio's a great host! His replies were always prompt and helpful.
In particular, he was kind enough to help me liaise for private transport to the apartment as I was traveling with my family from the airport.
The apartment is in a nice local area close to Tiburtina (which I think is not as chaotic and less queues as the Termini however still has great train access through Italy). I think it's a great area to be in as there are amenities and local eateries.
