Tasos' apartment was exactly as pictured. Very comfortable, conveniently located, and tastefully decorated. The views from the balconies and terrace were awesome, and the apartment was stocked with everything we needed (including a thermostat and both radiators and wall units for us to deal with the cool winter, which I'm not sure is common in Greece). You can walk to all the sights in Central Athens within 1 to 2 KM, and the surrounding neighborhood has cafes, restaurants, and markets within 0.5 Km.
Tasos was a very friendly and helpful host. He gave us tons of restaurant, bar, and sight recommendations and everything we checked out was excellent. We would definitely stay here again next time we are in Athens.
