We enjoyed Kas and this hotel so much that we stayed an extra night! The staff were helpful and friendly, especially if you chat with them a lot. The hotel is very, very clean and pleasant. Our room was sunny and cheerful and medium-sized. It is located just away from the town center, a very short walk. We never had any noise. They booked a kayaking trip for us that worked out fine (By the way, the underwater city = not impressive as all the tourist brochures try to promote), have a laundry service, but also told us where we could get laundry done cheaper, and they have a big breakfast with all the Turkish standards, and a fancy capuccino machine. There is no elevator, but the hotel owner told us that he specifically put us on the second floor because he likes to save the first floor rooms for older visitors, so they are pretty thoughtful and considerate. When we left, one of the owners gave me a flower and a pepper from his little garden boxes on the front steps.
If in Kas again, we would definitely return to the Sonne hotel.
