Hello Kaz,
Last year we stopped in Golden Dreams, just over the road from Sunny Dreams, but my brother in law and his family stopped in Sunny Dreams. We spent most of our time in Sunny Dreams as the pool was not in the shade and the bar staff Stan and Toni were fantastic.
Infact it was so good, that this year we are all staying at Sunny Dreams. The center is about 15 mins slow walk away, once you find the shortcuts so you are far enough away from the bustle and noise but close enough to it to walk in. The apartments have all the basics that you need, but we only had breakfast and tea and coffee in the rooms, the rest of the time we ate out. There is a large supermarket just over the road from Sunny Dreams and you will not believe how cheap everything is there.
The apartments are spotlessly clean and cleaned regularly. We have nothing bad to say about these apartments, that is why we have booked up to go there this year.
This will be our third visit in three years to Sunny Beach as we love it.
The people are friendly, the food is fantastic and the alcohol is cheap.

What more do you need ? Oh and the weather has always been kind to us, but that is something that can change.
I would say go for it as we have nothing bad to say about these apartments or the resort itself.
Have a good time.
Paul
