I had spent a week at the apartment and had a great stay.
Location
the apartment is almost directly opposite the tram/Bus station, and trams are abundant to and from the centre of town (20 minutes, 1.5 euros). There are supermarkets and some very affordable restaurants close by.
Apartment
The apartment is of 5 star B&B quality. It is extremely private with limited or no interaction with the host/other guests, although the host is always available via telephone, email or whatsapp for any assistance. The air conditioning and en suite bathroom and toilet, as well as private bar fridge and tv, really make the room a cut above most others places I have stayed at using airbnb. The apartment is also located in a very nice block.
Host
Luigi is the perfect host. He had gone the extra mile to provide and explain maps of the city AND the immediate area as well as good recommendations of things to do, places to eat, etc.
All in all, a perfect stay, and a definite place I would stay at if (when) ever I am in Rome again.
Thank you Luigi
