We stayed a wonderful month, so understand things well.
1: the owners went the "extra mile", providing gifts of some food, drink, ... when we arrived.
2. the apartment is very comfortable and the kitchen is really well equipped. They provided beach towels, but not chairs. We cooked almost every meal without difficulties.
3. The apartment complex is very well maintained, with mostly permanent residents.
The location is both a blessing and a curse. For us with no rental car, we relied upon the tiny market 200m away. The hike over the hill (we did 3x) is 45 min each way and exhausting! There in only one restaurant around also, so a car is needed. The + is that it is very quiet and beautiful and the beach is so nice.
Beach: it's a 3 minute walk. The close, left (west) side is really nice and has good snorkelling 200 m out: turtles, urchin, eel, lobster, many fish. The east side near the unpleasant "secrets" resort is not nice: no beach, stinky, and often loud party music. The area is doing rapid renovations to return this to a luxury area after the 2017 hurricane.
Our only complaints would be the mosquito trouble inside the apt and the bath drain smell. We just moved to the orient bay area and really miss anse marcel.
