Location of the property, no screaming kids and the pool / outdoor kitchen area. The property met all of our needs and the owner would clean the grill, etc. after use. There was also left towels etc that could be used. This is to do with the price, but a service they gave us! Very friendly and helpful udlejerpar.
The only drawback, and it is not really self-inflicted. When the property is up a mountain, there is not so good possibilities for walks. But again, very small minus!
