Montezuma Costa Rica

Planning on a few days at the beach at Montezuma as a perfect end to a three month trip here in Costa Rica.
Budget is now pretty low !! so looking for a low cost but clean and comfy guest house or B & B.
Looked at so many websites I just got a longer and longer list !!
Any suggestions from anyone who may have first hand experience of the area ?
All tips greatfully received.

Let me have a think...

Do you want a cabina type thing you can do self catering in or more of a b&b, or even a backpacker share a room hostel?

Do you want to be in town, can be noisy at night or is a kilometer or so walk ok?

Roughly what's the budget?

Not knowing any of the above, I would do the self catering cabina type places (in no particular order):

Hotel Los Mangos
Agua Vista
Casa Colores
Linda Vista

No guarantees though!
