Great location: 15-20 minutes walk to Acropolis and museums. Few minutes walk to the nearest grocery store. Big room for travelers.
Great service: Lucas helped me find website to order online tickets (bus and ferry) in advance to Zakynthos. He also helped me arranged taxi from airport to his apartment, very helpful for late arrival. He responds very fast.
The only drawback is you need to pre heat the water for around 30 minutes before you take a shower, but I am OK with it since everything else is great!
