The apartment was just as described on the ad, and everything was ok.
Concerning the house, there were just a few details, which could had enhanced our stay.
First of all, the lack of "hanger" for the shower, made it really hard to take a comfortable bath.
Second, the keys of the garden's door, and the house's ones were really tricky, and sometimes it took a while to finally get them opened.
Last, there is no wifi (and that is clearly said in the ad), but what is not said is that is not that easy to get free wifi around Trastevere, for you have the time to seat in a bar/restaurant (and order something more than a bottle of water) for them to give you the pass. As a traveller, it is a almost a must to have access to the internet nowadays, for looking up for the basics (opening times of places to visit, getting maps from the city, information, etc). So it was kind of an issue not having wifi on our house.
As a positive thing I would like to remark that, although the house is in the heart of Trastevere, this wonderful neighborhood, full of life, cultural activities, and nightlife -which can be noisy sometimes- there is a really quiet atmosphere inside the house (and even in its garden) as it is located inside a nice building, away from the noisy street.
Concerning communication, it was really complicated to get to Mauro when we first get to the house, which ended in both, he and us, wasting an hour and a half waiting for the meeting. We wrote Emmanuella at our arrival too, as Mauro wasn't answering, and she didn't answer either. Actually we didn't know anything about her un our 5 nights stay.
All in all, we would reccommend this house for two, specially for its location. We had a great time here! (:
