I arrived in Rome quite late, at around 11:30 p.m, due to a delay in my flight, but thankfully Riccardo provided very clear instructions (with pictures) on how to get the keys and on how to get inside the apartment building and ultimately the room. The room was very clean and there were several amenities like A/C, shampoo and soap and a hairdryer. The common space was very tidy and clean as well, and the breakfast options were not varied, but they were of very high quality.
The location is great if you like walking, if not you can always take the metro or a bus to which you get to their stops in under two minutes. The area is very safe (I think), but after 1 a.m. it gets kind of sketchy. All in all I highly recommend this place if you are looking for a great stay and also if you are a solo traveller, like myself.
