The communication went great and, although I haven't had the pleasure to meet Nassos he gave very clear and detailed instructions on how to find the apartment, check-in and check-out with ease. The place is cozy and nicely decorated, in a generally quiet and very authentic neighbourhood, short walking distance (5-6 mins) from the metro station Petralona. Very clean, ok wi-fi, great value for money, I would definitely stay there again!
