I took my advanced open water with Big blue and I felt welcome the minute I walked in. Very very friendly staff!
They were very good at guiding you throughout the dive, I felt very safe and in good hands.
The equipment is in good condition and the rooms they offer for free (on diving nights) are very comfortable as well. Fairly big, good beds, clean and nice bathrooms.
All in all a good place to do a dive or take your certificate!
