Marietta's house is very nice and comfortable, like we imagined, and she is very helpful, as are all the members of her family who live in the same building. We had a Greek salad, pastries, wine, beer and everything you need for breakfast on the table when we arrive, it's so thoughtful! We liked this place a lot and would recommend it to anyone :)
Also, the location is great, not too far from chains and platanias, 2 minutes away from nice beaches and very quiet with a beautiful terrasse. You should book it without hesitation!
