I would describe Katrina's apartment as a luxurious, wonderful place to stay, that's a pity that we had to stay there for one night only, I would spent there at least a week!
The apartment was big and clean and all the stuff we needed were there.
I can say nothing about the beaches in the near, because we didn't visit them, instead we used a great swimming pool with clean warm water. And we were alone there (in the swimming pool, I mean), it was great as well.
I would definitely recommend Katrina's apartment for everyone, for the price it costs it's a bargain.
