Dimitris apartment is very nice and I would recommend it!
It is close to Plaka (10-15 min walk) in a quiet neighbourhood. Supermarket and some restaurants/bars are within 5 min walk. I very much liked the lemon tree garden. Dimitris and also his mother are very welcoming. I could even check in earlier. Dimitris helped me book a trip with a good and trustworthy agency. They are very willing to help, but also give you your privacy. The apartment is big enough for 2-3 persons, is clean, the shower is a bit small but (especially in summer) the airco makes up for it. Like to stay here again!
