This is a spectacular way to experience Sayulita. Sitting in the dipping pool and watching the afternoon thunderstorms roll in was an experience we'll never forget.
This is a perfectly equipped space for two - the views, the kitchen, the bedroom, the living space, I would change nothing.
The hill to get to and from the location is no joke but my wife and I are athletic and to us - it was an attribute not a detriment!
The hosts were wonderful - they delivered flowers and a treat to help us celebrate our 10 year anniversary. Information was plentiful and clear.
The only reason I deducted any stars above is that, maybe I misunderstand what a "guest house" is, but to avoid any confusion for others - this is a suite in a house. It has a separate entrance from the other two units, but it is not a standalone guest house. But - despite clients in the house above, we never felt a lack of privacy (some of that was luck, though!).
As long as that is clear up front, and that is something you're looking for (you can rent the whole house if you like, which has 3 rentals in it), I would recommend this place to stay, hands down. We will be back!
