We stopped by this hotel to take a quick look to Huatulco. The hotel is a walk distance to the harbor, it has a nice pool and the staff is really kind but not so helpful with locations.
The rooms are another story, a weird one. We stayed in a room almost at the top floor (no elevator), and the room was divided in two with the bathroom in the middle. The WC was inside the shower (first time I see this) and there was no door between the bathroom and the bedroom, only the shower curtain divides. If you are with family or couple you "might" not have issue with this, but if you are on business trip or with friends this will be a problem.
Restaurant Tip: Go to the Harbor there are a lot of tiny restaurants around (not so cheap)
