Maria was very nice and explained the flexible self check in before our arrival. The apartment is located in the beautiful Plaka district of Athens. We felt like locals when we were having breakfast at the terrace with the beautiful view. Every sight is reachable by foot and within max 10-15 minutes so the location is really incredible. We loved the apartment too it was well equipped, very clean and had a nice size. I would really recommend staying at Marias to everyone. Greetings from Vienna :)
