The place is amazing. Is the perfect Costa Rica escape. You have a desert beach a few steps away from you room, the pool is incredible and the isolated vibes is perfect to disconnect from the world. Friendly staff and a big shout out to Diana, the owner, who is very careful and welcoming. The room is great, comfortable and spacious. The only note we have is regarding the shower: the shower wasn’t the best, it was lacking some maintance. Other watch out for people is that to get to the hotel you need to drive by a 5km unpaved road, so it takes a while and make things a bit far, but if you are looking for a disconnection I couldn’t recommend a better place. 100% would stay again.

There is only ONE thing that caused 2 separate problems. The staff is not intimately familiar with reading the room numbers on the room keys. Our party of 4 arrived and were directed to a building on the property with two separate room keys. One key did not match any room in the building and the other key matched an OCCUPIED room in an adjacent building. Frustration at the least and a potential security issue. The key issue was eventually resolved…..eventually. Our family finally settled in. At one o’clock in the morning, I was awakened by our sliding glass door opening. It was a drunken group attempting to enter our room. Apparently they also had a key to our room. Fortunately, the group realized they were entering the wrong room. The site appears to hand out keys randomly or has multiple duplicate keys. Aside from that the view is lovely and the swimming pool with swim up bar is awesome. Beware of security issues. Be very aware.
