Sadly no longer providing diving services, but there are literally dozens of such companies scattered all over the Sairee area anyway. The hotel shows its age, but is nevertheless a pleasant place to stay, with a roomy balcony, working shower and wifi, and both a fan and aircon, at least in my superior room. Very centrally located, with a plethora of (quite similar) restaurants immediately nearby. The pool is nice, and there is a gym eight minutes’ walk away. And the accommodation is relatively cheap. Would come back.
