I highly recommend AWS. I booked the two-hour day course. The staff are friendly and helpful. My questions via email beforehand were answered promptly (some very positive feedback like "We're over the moon to inform you..." seems a bit exaggerated, but was definitely well-intentioned). The organization was good. And most importantly: I had a lot of fun with the course and it was really beneficial. (Advanced beginner probably best describes my level). The three instructors on site were friendly and competent. I worked especially with Ansan, who took special care of the newbies (as opposed to those who had already been there the previous days). He was super friendly and motivating, gave a good introduction (helpful, not too short, not too long), and then gave really good tips for practical use in the water. I would book another course immediately.
