The overall stay was good, the place itself is a small apartment complex divided into 3 suites. The room we stayed in was very small but pretty clean. No A/C turned out to be a bit of a problem, since the only window in the room was facing the inner yard (once you enter the building there is a small yard inside) and we didn’t feel comfortable leaving the window open, since the rooms are located on the ground floor. So it was either sleeping in a hot room with no air or leaving the window open and hearing every noise outside.
The room was pretty clean, but there still were some things that could be improved in the bathroom (one towel had some stains on it and the shower cabin had some hairs on the floor).
The location is nice, but note that even though the apartment is located in the centre of the city you still have to walk solid 30 minutes to get to any tourist hotspot (Colloseum, Trevi fountain, Spanish steps, etc). The only spot that is near is the Borghese museum.
The parking situation is rather complicated since every single spot is taken almost 24/7 and eventually parking on the paid blue lots is not the cheapest per day. We were lucky to cruise through the neighborhood and find a tiny place 2 blocks away, so try driving around for some time.
The only thing that wasn’t that good was the check in process, since we were driving from Tuscany for several hours and had some tours planned for the day, arriving at 14:00. After asking for a 14:30 check in instead of the standard 15:00 one, we were told that moving the check in time even for 30 minutes costs additional 25€. Seems weird since that kind of problem has always been solved by the keylockers during all of our previous stays with flexible checkins. Eventually we had to leave all of our luggage in the car and paying for the underground guarded parking + sprinting to the place in between the tours that we had arranged beforehand to squeeze the check in in between.
The host is nice though.
