We came down as a large group and rented both of Netjy's condos. We had a great time. The condo's are about a 20 minute drive from San Juan, and 15 minutes or so to Walmart, so you definitely need a car.
There are some great little convenience stores and roadside fruit markets right outside of the complex, so you don't need to run to Walmart very often.
The beach chairs and cooler that she had for us to borrow were great. The kitchen was equipped with all the basics. We enjoyed the pool table on the upstairs patio.
The air conditioning in the master bedroom was a little weak, but I'm guessing that Netjy has that fixed by now.
The water level at the beach right outside the complex gate is pretty high, so there's not much sand, but if you walk down 50 or so yards, there's more beach to play on. The pool is beautiful and we had it mostly to ourselves, especially during the week.
The security guards were always pleasant and helpful and we felt 100% safe at all times.
We'll definitely be back and would rent this condo again without hesitation!
(A note on rental cars- use a well known US based brand - Avis, Hertz, Budget, etc. Second rate ones like Ace, Fox and the other little ones subcontract with local rental agencies who will try to screw you out of additional "insurance." We rented three cars from the big guys - cheap and all we did was tell them the name of our full coverage provider back home and we were on our way. The fourth person who rented a car went through Ace who subcontracts with Charlie's Car Rental and they would not accept even his insurance card- they wanted a copy of his actual policy or $20 per day! - that's more than the rental cost!)
