My wife and I travelled to Sunset Bay Club with some friends for a week in February. The grounds were amazingly well kept, the rooms were clean and well maintained. We stayed in the Suite, which is a separate little building. It's a large room, with a large bathroom and a big walk-in shower large enough for two.
As I saw in another review, the water is cold in the morning. All of the water heating that I saw on the property was accomplished by solar, so obviously it will not be warm early in the morning. By late afternoon, there was plenty of warm water for a shower.
SCUBA training was accomplished by an outside contractor, who was very professional and patient. I got exactly the amount of training that I wanted and needed for a short dive, which was all I wanted to accomplish, and the price for this was reasonable.
Dining was outstanding, the Restaurant offers a wide variety of local and international foods, all of which were great. There were usually several choices within the "all inclusive" menu, so if you didn't want to try the local meal you could always have something else that was good. The all inclusive plan includes alcohol, which is a great deal. Beer, wine and several types of mixed drinks available anytime the restaurant is open, which is basically all day every day.
The staff is very helpful, and knowledgeable of the local area. They offered to arrange for transportation, for sightseeing tours, for SCUBA, snorkeling and whale watching.
There is a nice pool and a Sauna, which I did not use.
There is no internet in the rooms, but there is free WIFI near the reception area.

We enjoyed staying here because it was a nice break from the very basic local food and simple accomodation we had found elsewhere. The meals were really fine. The proprietors are Belgian and there were lots of European people staying here so the atmosphere in the restaurant was relaxed and elegant. Staff were friendly enough.

While looking for a dive package to Dominica we found this location through our travel agent. The website shows a pretty little beach front property and has some photos and information about the meal plans and packages. Unfortunately it does not accurately describe the room accommodations which are simple to say the least. Our room also had no air conditioning and we woke to no hot water. The resorts excuse was that it was all on the website. The property caters to larger families and very small children could be seen and heard at all hours. When we booked we paid for boat diving, after we arrived they informed us the dive operation would be closed one day. We were told we could shore dive instead, which is free and unlimited. No credit was ever offered or received for the cancellation. We travel and dive extensively and never have we been so disappointed and felt more cheated after a vacation. The accommodations were not as advertised and were entirely unacceptable. If you are paying for budget you expect budget. In this case you pay a premium and leave feeling completely cheated.

We stayed 8 nights in this hotel. It is definitely a place that grows on you the longer you stay. The owner/managers are very sincere in their dealings with the guests, ensuring you get to do what you want. They have their eccentricities [imagine running this place for 12 years!] but they are mostly positive ones. As for the hotel itself I would summarise it as follows:
Positives
1/ Value for money is outstanding. So we were thinking of things in £ terms but even so, for a family of 4 on full board basis, we paid £110 per night.
2/ Sincerity of the owners - in a quirky way they will help however they can. You only feel this as you get to know them better!
3/ Location is great. Okay, so you do not have a golden beach but instead you get a real experience - grey sand, pebbles and small rocks just offshore - all of which means it has not been manicured and prettified, but does mean lots of tropical fish if you take a look.
4/ Wildlife: great to have the lizards and iguanas roaming around as well as the humingbirds [3 species], bananquits and the bullfinches coming to the tables. [No doubt some will not like the occasional "iguana pooh" on the walkways...]
5/ Rooms and cleaners are excellent. Even the waiting staff, at first morose and crotchety, become more friendly as time went on. By the end we found them very decent indeed!
6/ The lobsters we ate. Yum. We had them twice [took a bit of pestering to get them twice as they are no so much rarer than before]. You would pay £20+ for one fresh[ish] lobster in the UK. At Sunset my wife and I ate 8 between us each time.

Things to work on:
1/ The meal / manu variety needs more input. We heard many complaints [mainly from the guests from Martinique nb French] that the meals were not up to it. I have to say chicken drumsticks were in abundance - where the breast meat went I do not know!
The evening meals do need a bit more variety / imagination, but I will say that what I ate was always tasty and good quality.
2/ Swimming pool was just about ok. Not that clean and one or two sharply cut tiles made for a hazard.
3/ Rooms nice and clean but could have been a bit larger and more sympathetically made [more use of local timber / set diagaonally to give a more individual feel].
So on balance I would give the place a thumbs up.
