I stayed with my family (4 people)for one week at Konstantinos' place. Everything was exactly as described in the listing on the site of Airbnb. Apartment was clean, convenient, safe and all amenities as described.
Konstantinos is a great host and always available. The apartment is on the ground floor and only 8 min walk from the Petralona metro station. It is a near proximity of a bakery, couple of supermarkets and grocery stores. The neighborhood looks safe and quiet.
It is a value for money!!!
