My girlfriend and me absolutly enjoyed our stay in the garden view house and we had a overall awesome time in Ialysos. To the apartment I can say, that it is very clean and nice decorated. But the best thing is the big garden and the terrace.
To future guests I would recommend to rent a car or - even better - a scooter. Otherwise you will have to walk for a while to get to restaurants, supermarkets, etc.
Mariette is a very nice and kind person. What I appreciated most was, that she let aus stay the whole last day in her apartment, because are flight went in the evening.
We would rather have stayed some more days.
