THis is Todd from Victoria, BC, I was in Costa Rica and kited Bahia Salinas for 2.5 weeks in January.
For the prices that you can fly to Liberia, CR, from Montreal, you should REALLy book a trip right away. The area is quite beautiful and the vibe is fantastic. All three hotels are good and I would stay at any of them. I stayed at BlueDreamHotel.com and would stay there again but you have to buy 3 meals a day at restaurants. If you stay at KiteHouse (Kent's)or at CometaCopal (Bob's) in most cases you will also have access to a kitchen.
The links that Ocarina posted are correct:
Trois bons hôtels sur place:

I will be going back to Bahia Salinas next year or the year after. After seeing my photos, next time a few friends will be joining me and my girlfriend.
The area is super safe but there is no nightlife. That was ok for us though because we were so tired from kiting everyday on 5m-9m kites and were in bed by 2100. One of my friends did have some cash stolen from their room while at KiteHouse but I do not know the details of the incident.
