The apartment is pleasant: clean and comfortable and quiet. Everything works (hot water, fridge, oven and hob, Air conditioning etc), the doors all lock etc. The bed is large and the matress is lovely a firm! The place is REALLY close to the beach, which has the TripAdvisor.com prize for best beach near Chania and which is really lovely. The beach-front is a series of very friendly and pleasant bars and tavernas and it's an easy walk along the sea to the gorgeous Old Town of Chania. There are some really terrific restaurants on the sea-front right near the apartment so it's a great base for visiting Chania.
Kostas is very friendly and accommodating. I would recommend this place as a base for Chania - whether it's beach you're after or historic town.
