We were 6 people and stayed in the villa for a week. The villa is just like in the pictures and totaly met our expectations.
When you book you get all of the informations you need for Crete from Kostas via mail so you can plan things out. Check in and check out went smoothly. Pool, garden and house cleaning service was amazing and the people were very kind.
Chania is like 15 minutes from tbe villa. You have some restaurants and a mini market in foot range (7 minutes or so). Check out the restaurant "Nikos" for amazing food. They also have their mini market right next to it. Very kind people.
I highly suggest you get a rental car for everything else since the villa is on a mountain obviously and the most amazing places of crete like Balos Beach or Elafonissi are 1,5 to 2 hours with a car.
