We were group of 7 (aged 7-75) and stayed at Villa Jasmin for one week in the beginning of July.
The villa was just perfect, actually better than we expected. Kids loved the pool, and the view from the terrace upstairs is superb.
Location (some 5 km from Chania, 2 km from the nearest beaches) is quiet and peaceful, but still easy to access.
However, the best thing with the Villa is the owners, Kerstin and her husband, they were probably the most helpful and friendly people I've ever met. For example, we had both arrival and departure at nighttime, and they helped a lot to make this easy and comfortable for our group.

Recommended strongly.
