Myself and two friends came to Manchester for a weekend trip. We were disappointed with the security of the building and the lack of response from the host when we raised issues.
While the door to the flat locked, the door to the building from the busy street did not lock and the balcony door in the living room did not close or lock. This meant there was constant cold air and noise coming into the room with the spare bed in it. Both of these issues made us feel uncomfortable and unsafe. We tried to contact the host about these issues multiple times and, other than seemingly automatic messages, we were ignored.
More generally the flat had several maintenance issues (broken curtain railing, broken bathroom lock, flickering light in the bathroom) that had not been dealt with.
This flat could be a great property to stay in if it were looked after properly as it was in a good, central location and has decent facilities. However, we would not recommend it in its current insecure state.
