What I liked the most:
* great owner - very helpful and positive minded making it even more relaxed
* Very good place. Quite high in the mountains giving a cooling breeze (so really less hot than Plovdiv)
* Very nice views on the lake and hills
* Wooden sanitary buildings on concrete floor. Giving the camping a 'nature' atmosphere. Yet santory is really functional.
* Hiring canoes to make to tour on the lake
