I loved Samana and Las Terrenas. But there were not enough affordable flights to the area for me to put it on my list of places to live. Although it is such a beautiful area. I hear the golf is good too, but I don't play so I don't know.
Although I prefer Bavaro area because it is a close drive to La Romana and Higuey, and has a variety of beautiful beaches. It is also very tourist oriented. People complain it has no culture. But if you like beaches and pretty malls and going out dancing it is a good place. You can drive to culture nearby. The population is very tourist oriented and its gets pretty quiet in the off season. Prices can seem high sometimes compared to nearby Higuey, but its the tourism aspect. Also they are working so hard to pull the area together (sidewalks ect) The best part is - 24 hour electricity.
I'm a city girl, and I don't think you could pay me to live in SD, but I like being able to drive there quickly enough. I like to leave just as fast as I got there. Too dirty (unless your in a rich neighbourhood, even then...) Too sketchy. But some people fall in love with it. It is the oldest city in the Caribbean, so there is that....
As for Puerto Plata, Sosua and Cabarete.... I found it to be dirty, rundown, and sketchy. It seemed to attract a different type of people as far as tourists go. The mountains are gorgeous however, and the sunsets are the best I have seen on the island.
I am curious how other people feel about some of the inland places I haven't been to yet. I hope I don't get hanged for calling PP sketchy and ugly. I probably will though
