The staff was helpful from the time we were booking to the time we left. The rooms were nice - kind of a "bungalow" style. GREAT views. Breakfast on the porch staring out at the ocean is just amazing. We were told we went in the off-season (mid-November) so we got great rates and the weather was still great. Staff gave great suggestions for restaurants and nightlife outside of the restaurant. They also really pushed a lot of the tours - sometimes I'm into that stuff, but we were on a more quick, budget-friendly, relaxing trip, so we didn't really partake. Get to know the bartenders - it will pay off. Remember to treat people with the respect you want to be treated and most of the time they'll do the same.
A few additional notes:
We took a taxi to the bus station from SJU airport, then a bus to Manuel Antonio beach. It was WAY cheaper than a taxi or car service, and totally safe. Neither of us really spoke Spanish, so there was definitely some language barrier difficulties, but we made it, so it can't be that hard. If I went back, I'd get a friend who knows Spanish to write down things we needed for each way to make it a little easier. Manuel Antonio Beach is about 2.5 hours from the airport area.
Didn't use the spa or fitness center, so not sure if those are at the property?
Hotel has free wifi in a few areas, which is nice.
