We definitely enjoyed our stay in Alberto's accommodation!
The location is amazing, right in Trastevere, a district full of restaurants and bars and with the main sightseeing attractions (trevi fountain, pantheon, piazza Navona etc) not too far off by foot (makes for a nice walk :) ). Everything was well reachable by foot and we didn't really have to make use of public transportation which was nice. The check-in was super smooth and easy via a keybox and also for the checkout we just left the keys in the appartment.
I have one negative point based on the location: there are two cocktail bars RIGHT in front of the accommodation, so if you have trouble sleeping when there is noise and music (until 3-4am everyday, not just on weekends) this might not be the perfect fit. Me personally it didn't bother, but my friend had trouble sleeping every night until she bought ear plugs. So something to consider.
But apart from that it was really lovely, cute appartment and with an amazing location! We really enjoyed our stay here :)
