We spent four comfortable nights here. Montezuma is all of two or three blocks long and chock full of restaurant,housing and beach choices. There are hostels for backpackers and high-end choices for people who want saunas. This is a reasonable choice for people who want economy along with comfortable mattresses, a/c, wifi and cable. Be aware that you'll need to buy drinking water everywhere.
The prices quoted by other visitors for their rooms may have been low season rates. We paid more. Ymmv.
Also, this part of the coast is experiencing a red tide. If you're coming soon, check whether it's still here.
We were lucky enough to stumble across a turtle conservation station on the beach on a day they were releasing turtles into the ocean. Totally unexpected thrill.
We also loved the waterfall just a ten minute walk from the center of town. The climb is a little harder than I expected, but there's a lovely pool near the beginning of the climb where you can sit in the water and wait for the more intrepid in your party who want to make the whole climb. Remember to wear good shoes, a bathing suit and a hat. Lovely!
