We had a great time at Kleonis place. The apartment is spacious and beautiful and the roof terrace is both very large and has a 360 degree view of the old town, the mountains and the harbor. I would recommend it for anyone who is traveling to Chania.
Some additional info that we not could find on air bnb:
-there is parking right outside the door or at a neighborhood parking lot a few meters away, where we could find parking the entire week.
-There is AC in the living room, kitchen, in the bedroom on the ground floor and in large bedroom on the second floor but not in the other bedroom on the second floor.
-There are two bathrooms (wc and shower) and one toilet (only wc)
-We were told not to use the elevator
Thank you Kleoni and George!
