We were staying in Montezuma and stopped at Celaje for lunch. We found the female owner who was working the restaurant to be *so friendly* so I'm baffled at the people who described the owners as cold and aloof. She made us a wonderful lunch, and invited us to have a swim in the pool, she said it was the slow season in Costa Rica (late November/Early December) so she was glad to have some extra people around. We enjoyed lunch and a swim in the pool, she had the cutest little dog who we played ball with. We enjoyed our time there so much we came back the next day for dessert, drinks and another swim. The place seemed so laid back, relaxed and friendly. I'd love to go back and stay there someday!
Again: I did not stay at the hotel, just used the pool, and had lunch/drinks/dessert. But our experience of that was great!
