Andreas communicated with us over airbnb and a chat group, and he remained very prompt and helpful in his replies! My husband and I stayed in his airbnb for our honeymoon in Rome, and we had a fun time. The apartment has a wonderful hot tub, as well as sufficient cooking amenities for a simple meal. It felt safe, spacious and clean. When we had some issues with the bathroom as one of the hooks fell off, Andreas arranged for a handyman to come to our apartment to fix it immediately. He also arranged for a private transfer for us to and from the airbnb to the airport/ train station, which made things more convenient for us. All in all, we had an enjoyable stay! As a side note, as the Trastevere area tends to be more lively, you may be able to hear some noises from outside at night. Also be aware that it is difficult to do laundry in the room however there is a good laundromat nearby called Il Mastello.
