Just yesterday I was thinking I might be able to knock Costa Rica off my bucket list soon. I checked out accomodations on airbnb and thought I might look into this place more. Everything seems to be there ie. Surfing fishing, beaches etc. with a small town feel at a reasonable price. October calendar looks to be wide open. I suggest checking this link out by yourself first though. Once the mrs. sees the vistas from the rooms you may have no choice.
