The apartment was what I expected very cozy and nice flat with everything you need. Very bright and clean. The apartment is for 2-3 people.
The host was online, and we have no problem with check-in/check-out.
It was not surprising that there was no elevator (the first day was a little bit hard) but it was not the problem all the other days.
The location is near Termini Centrale (10-13 min), Termini Metro and Termini Bus hub are very convenient if you plan some excursion near Rome and also from the airport to the apartment and back.
The thing that I didn't like about the Termini Central location is all these miserable and strange people and it was inconvenient to come back home late at night. But still, save.
In the closest area where some supermarkets and restaurants.
