We had a wonderful stay with Daniele! Communication was quick and friendly, and he was very accommodating to us which made the whole thing very easy going.
While the neighbourhood might not seem like much at first, it's actually very welcoming and friendly. As two young adults there wasn't a moment we felt unsafe, even if we were out late at night. Everything you could want or need is within walking distance, and if you don't mind lots of up and down even the historic city centre is walkable at about 30 minutes.
The room is exactly like it is presented on the page, clean and just right for two people. We didn't use the kitchen, but from a quick glance it seemed fully stocked. The room stays pretty cool even in warm temperatures, and it's located on the second floor so if you open the windows after dark, it catches a nice draft.
It is slightly noisy, as in you can hear other residents flush the toilet or use a hair dryer, but we didn't have any problems with overly noisy neighbours so couldn't tell you what it's like if someone decided to have a little party.
Really our only thing was the bed - the mattress was very hard and the pillows quite thin. There is a small couch in the communal room, but in your own room the bed is really the only place to wind down and it wasn't too comfortable. Luckily you'll get somewhat used to it and Rome will tire you out enough that you'd be able to sleep on the floor, but it would've been nice to have something a bit more comfortable to crash down onto.
Overall we had a really great stay here, it's a good deal for its price and it's a great, central location.
