Visited here one Sunday early evening. Not so hard to find, and through the front door are another four doors or so, Baan Thai is back right.
I rang the bell, was buzzed inside and climbed the stairs to a lounge. I was greeted and seated, and shown the menu. I took the hour long hydro massage, which was €80. I was offered the choice of four girls, and chose Tea, small, slim with long dark hair.
She took me back downstairs to a comfortable room with bed and bath, and after filling the bath invited me to step in. Then she stepped in with me and massaged me for about twenty minutes, encouraging me to touch her.
After this fine experience, we dried off and she gave me a good massage with very good happy ending.
Recommended if you're in the area.

Hedgehog....thanks for memory. Baan Thai provided me with my very first action in NoordNed when I moved to Groningen 5 years ago. And very nice it was too!
