I have traveled in D.R. and my expectations are low. This place is fine, but it is overpriced. Right on the beach, but too dangerous to swim, the pool is reasonably maintained. The AC works, bathroom door closes (many do not), shower water is tepid at best. No safe, no refrigerator, no daily housekeeping. Breakfast is mediocre (scrambled eggs and a roll, no fruit), and I was upcharged for a second cup of coffee, ridiculous. Overall not too clean. In short, just like any cheap hotel except it isn't cheap, I am not going back.
The area is primarily of interest to eco-tourists, the bird-watching is excellent. But it has problems for the visitor: few restaurants, empty and overpriced. Try Duck's Restaurant in (wait for it) Los Patos, it is clean and reliable. No grocery stores, some fruit available from street-vendors. Plantains everywhere, but I did not see a banana in 5 days visiting, strange. I recommend you buy food in Barahona before heading further south.
