The location is ideal: a 5-minute walk from a nice park, a 10-minute walk from the Colosseum and the subway, a 5-minute walk to restaurants and gelato and espresso, and away from all the tourist mayhem. We are travelers who don't like being smack in the middle of all the tourist chaos, and we loved the location. Matteo had maps of the area and the subway for us: super helpful.
The outdoor space is an unusual find in Rome! We enjoyed the patio on our first afternoon, sipping wine and eating pecorino cheese and tomatoes that we had bought at a nearby market that Matteo told us about, before heading over to the Colosseum.
(Sadly, a rare downpour prevented our using this space again. During the downpour - which was truly spectacular, shutting down the Colosseo and the Forum for the day - many of the older buildings in Rome leak around the windows, as did Matteo's. This was a minor inconvenience, but we mention it, because tourists should be aware. Matteo was very attentive, and did what he could to fix the problem. Many AirBnb landlords have umbrellas handy for their guests.)
Living space: Ample room for hanging clothes, convenient area to place open suitcases. Dining table with plastic chairs. Couch and large screen television downstairs. The sleeping loft is a little tricky - steps are rather shallow, and the ceiling is not full height, so we bumped our heads a couple of times in the middle of the night when half-asleep. The bed was very comfortable. There is a fold-out couch downstairs, and we didn't try this as a bed; but a bed downstairs might make more sense so that you don't have to go up and down the stairs in the middle of the night to use the bathroom. In our opinion, little kids would not be safe in the upstairs loft.
Kitchen: Small, but has all your needs - microwave, stove-top coffee-maker, oven, stove, fridge, freezer, wine/beer bottle opener. We would've liked some wine glasses, but we just reused water glasses for our wine. We didn't use the washing machine, but for a longer stay, that's a useful amenity.
The property has a private entrance for guests (and there appeared to be 3 guest rooms. Matteo and his family live upstairs but use a separate entrance.) Guests have to slam the doors and gates to get them to shut, which isn't ideal, but it didn't bother us much.
Bottom line: We loved our stay here. We would recommend it. A few added conveniences such as towel hooks, a soap dish in the shower, wine glasses, etc would've helped but were not enough to prevent our having a GREAT time. Matteo is kindness personified and was a very attentive host. The 45-euro ride to the airport is a great offering, and Matteo arranged for this for us.
