Constatinos's place is right in the middle of a very lively area. Ermou street is right around the corner, so you can easily walk to the center. Also the metro is literally 2 min away, with easy connextion to the airport and port. The apartment is spotless with everything you need and even though we didn't get to sit there, the terrace is nice as well. The openair bars and clubs are definitely loud (we stayed only for the fridaynight), so if you are staying on the weekends, either visit them or bring earplugs :). Constatinos wasn't able to meet us, but his mother welcomed us and we got to talk to him on the phone when entering the apartment. His mother also let us leave our luggage in her apartment the next day, before leaving Athens. Recommended!
