We stayed in Lefteris' place for 3 nights and it was perfect for what we needed. Both Lefteris and Zannis (co-host), were great to communicate with and met us at the metro which is only a 5 minute walk from the apartment. The area is perfect, away from any tourist action, but only 10 minutes from the Acropolis and in a lively residential neighbourhood with locals, great bars and restaurants. As we only had two days we stayed local after our time exploring during the day and found the area to be really interesting and lively.
The apartment is quite unique and perfect for 2 people. The outdoor terrace/kitchen is great for breakfast in the morning, and the place is fully equipped. It even boasts a, albeit obscured, glimpse of the Acropolis from a corner of the balcony!
It was the middle of July when we stayed so a bit warm for the outdoor bed, but the air con inside was perfect.
We would definitely stay again when back in Athens.
