A pool in San Jose area needs to be heated! I am not sure if anyone goes in the pool at Finca Rosa Blanca. It was cold and full of keavesduring my stay, so be sure to check recent comments there and elsewhere. I was able to use the ADR pool, although they are quite small, and the ocean was nicer IMO.

It's surprising how cool it can get in the San Jose area. We had dinner at Xandari one night, and they actually came around with blankets for everyone in the restaurant.
