The location was really good, at the city center but not at a crowded street, so there were no loud noises. The metro station was on the same street and It was really easy to get to the airport. Emmanouil is a very good host and he sent me messeges with useful information.
However, the access to the apartment was dirty, the elevator is a little scary and old and the walls are thin. We were lucky and the neighbours were not loud people but we could hear them clearly.
The apartment is small, but that is not a problem because we were only there to sleep. Also, the cleaning was not as good as we expected.
