We we very pleasantly surprised with Hotel Alamar. Our room had lots of light, was clean and everything worked (a/c, TV, safety deposit box) and the WiFi was excellent.
We enjoyed the pool and the breakfast.
Staff were very friendly.
One small thing: When we packed up to leave after two nights (after all, Puntarenas isn't the most interesting place to stay), we noticed that the safety deposit box sitting in the wardrobe was loose and not attached to anything. So someone could have stolen the box and its content.
