We stayed at Eleni's place for two nights on a quick stop in Athens. The apartment was very clean and had all of the amenities for a comfortable stay. The location of the apartment was awesome! Easy walk to the Acropolis area, restaurants, shopping, and very close to public transportation if you wanted to venture further, which was great especially if you have limited time in the city like we did.
We did have a little trouble finding the apartment at first. You may want to contact Eleni before you arrive to get more details. She was very helpful and responsive when we contacted her and we could tell she cared about giving us an enjoyable stay. I would recommend you stay in her apartment on your next trip to Athens!
