I stayed at the hotel for 2 nights on a business trip.
The hotel is a country club in San Isidro. It has a nice pool, hot tub, tennis courts, full gym, restaurants, and a casino.
Hotel: I was there during low season, so I pretty much had most of the hotel to myself. The hotel staff wasn't very friendly, but they answered most of my questions and made some effort to be helpful. Just not friendly. They do have secure, gated parking which is included with your room, and the hotel is on the Panamerican highway, so it is very accessible. The rooms are big and well kept. Some limited toiletries in the bathroom, but everything is clean. The AC worked well. The beds were hard - I sleep better in hard beds, but some people may find it uncomfortable.
Restaurant: the food was decent, though some dishes overpriced for the location. The restaurant staff was very friendly and courteous. The breakfast was a very typical Costa Rican dish, and overall food quality was good.
Gym: the hotel/club has a full gym where many of the locals are members, so it is usually packed. But it's a very complete gym for a hotel. I think I saw a personal trainer there as well, in case you need it.
