Apartment in ground floor located in charming Trastevere on a quiet road. We visited in November and unfortunately the humidity in the apartment was extremely high and it was impossible to create an acceptable environment inside. We had two dehumidifiers running non stop and found mould on the walls. We left after 5 nights and immediately our coughing decreased and our general well-being came back. We confronted the host but they didn’t accept our experience. They changed explanation from this as completely news for them to the mould being a matter of painting the walls. We didn’t stop confronting them and they stopped answering. We had to get help from Airbnb who did a sublime assisting job and we moved into a new apartment for the rest of our stay in Rome.
