I stayed with my girlfriend 3 nights in the apartment and we enjoyed every moment. The apartment is located in a perfect location, exactly as written - 1 minute to the beach and 5 minutes to downtown. The area is very quiet but in the same time very central, which make it a very pleasent place to stay (lots of restaurants, car rentals, bars, coffees in walking distance).
Regarding the apartment itself - it's very specious, with a big balcony that has entrances both from the living room and the bedroom, fully furnished, and has an A/C (in the living room, but it's poweful enough so you feel it when the door of the bedroom is open). Everyrhing is tidy and clean, and the decoration is elegant and thoughtful, so you get a cosy feeling. The only down side about the apartment is that the photos on Airbnb don't show the real nature of it (we thought we were going to book a budget place, it was far away from that - in a good sense. So we actually told Spiros he should upload new photos).
Spiros is a cool guy, and he really knows how to treat his guests! He gave us tons of recommendations, which we found out to be pin point accurate. We strongly recommend this pearl to anyone planning a trip to Rethymno.
