Our stay at Nassos' one-room appartment was unanimously wonderful! Nassos gave us a lot of information about Athens and hints on how to organize our forth and back from the airport to the appartment. We actually haven't met Nassos in person, as he left the keys for the appartment in advance and at the same time, he was very well and fast reachable via phone. The appartment had everything we needed for a pleasurable short winter holiday in Athens. He even provided a couple of English movies and several other features (cooking space, fridge, indirect light etc.) ensured our stay to be a round thing.
The neigborhood was very pleasant, quiet and everything necessary for daily supply was acessible within 5 minutes - bakery, small shop, supermarket and a very nice cheap souvlaki-pita place on the main road called "Souvlistas" (very recommendable!).
Nassos was very forthcoming considering our check out, so we could stay until late afternoon.
All in all - a perfect, cosy place to stay in Athens!
Thanks again, Nassos :-)
