I haven't stayed there, but while I was on holiday in June this year, a couple used to come into our apartments for a drink in the afternoon who stayed at the Private Hotel, they said that they loved it because there were no kids there. I dont know if there were no kids allowed, or whether it was just a coincidence at the time.
This was a couple in their late 60's and they said it was kept very quiet, especially in the evenings. They go there every year.
Hope this helps a little. Even if its not to your taste, its only a place to put your head down at night, and if its a bargan at the moment, I would jump at the offer.
