I stayed the first night in July Montezuma at the Sano Banana for $69, It's ideally located - right across from the Chico Bar but it was overpriced for what it is.
The second night and for the following five nights i stayed a few blocks away from the center of town at Luz de Mono and at off-seaon rates of $50 for a credit card payment or $45 cash I found it far better value. For one thing you are really staying in a rain forest, with howler Monkeys in the trees and Iguanas running around the swimming pool.
The breakfast is first rate except you have to be careful of a couple of magpie birds that try to steal the sugar packets and it does rain from time to time, sometimes a tropical downpour.
The rooms in the main building are adequate, with hot water and lots of space and decent Wi-Fi The casitats on a hill above the main building for about $15 more are really the ideal place to stay but the Wi-Fi doesn't seem to go that far, so I stayed in the main building.
The managers of the resort, two sisters from Bulgaria, spoke English and were very hospitable. I highly recommend the Hotel Luz de Mono for your stay in Montezuma. It's the best value and you really get the full rain forest Costa Rica experience.More
