Romina and George are absolutely amazing. We got a very nice welcome with a lot of tips from the locals, Romina made a fabulous guide that's waiting for you when you arrive that will definitely keep you buys for a couple of days (with hand drawn maps and everything). The house is very nice and the garden is lovely (if you like plants :)). The area where the apartment is located is very good for food/drinks (raki) and it's only a short walk to the more touristic-area(s) of Athens.
The house even had a little Christmas-tree as a nice little touch (we went in the winter).
Thanks once again Romina and George!
