I can help out here too, not that I've ever got to spend a full week there!! ;)
The PCV is my favorite hotel in Cuba, and I've been "bumped" to more than 1. To my mind, it has all the features of the PP, but in a smaller hotel, so it is less busy, and easier walking. The beach is, to me, the best in Cuba. Lots of sand in the middle, with rock and coral for snorkelling at each end, as well as having the best scuba instructors in Cuba!
The food is good, (and Don't miss the Japanese... ask for Luke he's wonderful!)
