You can stop looking at other places for your stay in Chania. This is hands down the best place.
Location is near the city but away from the narrow streets and noise and touristy areas. It is but 1.3km to the nearest beach and located in a quite and serene neighborhood with an excellent tavern next door. You can even see the sea from the house.
The house is newly built with a basement and 3 levels. Beautifully designed and thought out by the architect owner. Basement has a large bedroom with a double bed and toilet (plus laundry area with washer and dryer). Ground floor is the living and dining room with Netflix for the kids and an outdoor pool which is heated over spring and autumn. Level 1 has 2 bedrooms with a bath and level 3 also 2 bedrooms with a bath. I only wish my own house was as nicely built and thought out.
Kostas and Christini are excellent hosts, getting in touch via WhatsApp prior to the stay to ask what we need and how many are coming. Also preparing a baby cot at no charge for our infant. They were on hand when we reached really late (because of multiple factors) and we were amazed that our hosts had prepared spinach pies, loads of fresh fruits, bread and breakfast items like ham, cheese, eggs etc. There was even a Nespresso machine with pods, drip coffee maker, oven, microwave, induction stove and all the cooking utilities that you might need. There is a dishwasher with pods for washing. They were also super flexible about our check out time. The hosts are also super friendly and made recommendations as to where we could go to see the sights and where we could eat as well.
Cleanliness was impeccable - my wife who is Hygea's "disciple" was impressed. There are clean and really soft towels (1 large and 1 small) with embossed words (FOS villa) for everyone. There was a washer with soap all ready for use.
This villa is appropriate for large groups with children and the hosts are the best we have encountered to date (over various continents). Compared to the cramped and touristy quarters in the old town, this is a breath of fresh air. Go and experience it for yourself.
PS Sincerely and thoughtfully prepared to be a home away from home in every sense of the word!
