We sadly only stayed at the Chen Sea Resort for two nights, I'd have happily made it two months.
Myself and my wife were in Phu Quoc for 4 nights in total, just looking a beach, some sun and to over indulge on Vietnamese cuisine. We were spoilt.
We had a beachfront apartment, a small grassy area infront with a couple of hammocks and the beach right there 15 meters from your back door. The room itself is spacious, beautiful, simple and tastefully decorated, with closet space to keep everything out of the way to keep it clear and clean.
The staff are very attentive, you've not got a chance of trying to put a parasol up or move a deck chair before someone runs over to takeover. The options of having some basic watersports right on your doorstep anytime is great to go paddleboarding, wind surfing, snorkelling, kayaking etc.
As you are pretty remotely located you are reliant a little on the hotel restaurant, but that did not disappoint. Obviously nowhere near as cheap if you have the option of going into to town, but the quality is excellent, practically every dish we tried was just delicious. Breakfast also has great range of options for you to try.
Totally recommend the place, missing it already, can't wait to go back.
