I stayed in Villa Yannis for a week with my family - all in all, 8 people, 3 couples, plus one child and one single adult. The rooms are spacious and we had no problems fitting everyone in. The beds are fine and comfortable. Every room has air conditioning, but it is a little noisy and did wake us up from time to time. I hope Yannis will figure out what was causing it but looks like there might be a time for an overhaul in that area. The bathrooms are a little tired and you have to step into the bathtub to shower using a hand-held shower, but everything worked fine.
There are two great restaurants within walking distance from the house. I'd recommend reserving tables there, especially on weekends.
We had two small cars which are essential in this area, as one would not walk to the supermarket, and there is a 15 min drive to Rethymno the nearest town. We used the car rental service recommended by Yannis and can't complain.
Yannis is extremely helpful and put all his effort into fixing the small things we pointed out during our stay.
