We enjoyed the stay at Yari’s place. The location is absolutely amazing - right in the middle of Trastevere, very close to bars and restaurants, but still quiet at night. The apartment is nice, very homey and large considering the location. It was very comfortable for two people. Cons: the cleanliness could be improved a bit (the couch wasn’t clean) and the wifi is not great.
Lastly, check in was easy and we appreciated being allowed to check in a bit earlier. It was difficult to reach Silvia or Yari when we first booked, but afterwards communication was easy.
