We spent 8 nights in #9 and had 4 adults and 4 kids (aged 11-18). The unit was perfectly sized. Arnaldo was fantastic at responding to every question and request we had. When we thought we had a water issue, he was there immediately to help us solve the problem. When we requested more beach towels, they were delivered quickly. The upstairs had a master bedroom with a bath and plenty of room for the boys in our group to have their own space (ages 11, 14 and 18). Downstairs had three bedrooms (one a master with bath), living room and a small kitchen. The kitchen was a little small to be very functional. The outside decks were nice and had good furniture for relaxing. The unit could use some updating overall. The bathrooms didn't have a lot of space for toiletries, which was a little difficult when sharing. There was a very nice washer and dryer available for our use. There are currently water restrictions in place every other day, which really didn't impact us much. We just took quicker showers and only washed clothes on city water days. I would recommend having Arnaldo show you how to work the water tank system if you have any questions on it.
The unit is part of a relatively quite complex with a beautiful beach out front. You cannot swim in the ocean in front of the complex because of the reef but the water is so crystal clear that it's great for exploring. We saw many fish, sea urchins and even an octopus. It is about a 15 minutes walk to Jobos beach, which was excellent for snorkeling, surfing, swimming and just relaxing. Because we had a car (which is a must), we also drove to several other beaches in the area. Crashboat Beach was super fun for the kids because there is a pier to jump off of. We also hiked to Survivor's Beach, which I would highly recommend. There are several nice restaurants and a grocery store within driving distance (although we usually cooked in the unit). There is also a basketball court, which our boys loved even though the rims need some work.
Finally, be sure to visit Old San Juan. It was one of our favorite days! Overall, we had a great experience in Puerto Rico and would definitely visit again.
