This is a great place and highly recommended. Lisa and Sophie are excellent hosts - their communication is quick and comprehensive and the best I've experienced using Airbnb.
The condo is steps from the beach and overlooks the resort's pool and outdoor bar. It is also a very short walk to the resort's restaurant, which is surprisingly good and fairly priced. The condo itself is nice and has everything you will need for 2-3 people.
The resort is incredibly peaceful - probably the most placid place I've ever stayed. After two days my girlfriend and I were very relaxed and extended our stay one extra night. If you're looking for a quiet spot to get away from it all, I can't recommend it more.
One thing to note: the resort itself is 10 miles north of San Pedro and the road turns into a dirt track laced with potholes around the fifth mile from town. Accessing the resort is easy if you take the coastal express water taxi from San Pedro, which is a beautiful ride. You can easily rent a golf cart at the resort to drive around, but there isn't much around the resort. A small store is about a 30 minute ride south from the resort and has basic groceries (and, importantly, lots of rum). We didn't try to visit San Pedro after we reached the resort, but it would take quite awhile if you tried.
Don't let that deter you - this place is great! I recommend just stocking up on groceries when you arrive in San Pedro and bringing it to the resort, so you don't have to rent a golf cart (although that ride was quite an adventure). If you rent a cart, I suggest driving north. After about a half mile, the road ends and you can drive along the beach to secluded spots along the coast. We also enjoyed the resort's snorkling trip to Ho Chan Marine Reserve.
Highly recommended - we hope to be back!
