There was some confusion upon check-in, but once it was straightened out the owner and manager were very responsive. The unit is in an awesome location, literally less than a one minute walk from Sayulita square, the heart of the town. Everything is within walking distance: Bars, restaurants, cafes, the beach. I didn't miss not having rented a car.
The place is extremely rustic, so be prepared for that. I'm not sure how it compares to other places. Hot water in the shower lasted about three minutes, but the bathroom is very unique. Also, no washer or dryer.
If you want an authentic Sayulita experience, I think this is a great unit for that. :)
