Dont know about privvy because i have never been, but new thai house (montra) is ok. Ive been a few times when it was still thai house (so over a year ago). It can be hit n miss. The biggest issue is you cant pick the girl, you get whoever is next in line unless you book a specific girl in advance. They all do decent massages as they are trained, but extra services are on offer with a sliding scale of costs.
If you are lucky you can get a fantastic girl and leave very happy, if not it can be a complete waste of money.
If you go would recommend you go for a massage and decide during that if you want anymore. Also remember its one pop only no matter how long the session or how many girls.
My first time anywhere was here a few years ago now, and i still rate that first one as the best time I've ever had, but unfortunately the girl left, and i never found her again. So would give the first girl a 10, but the others have varied between 4 and 7 out of 10 for services. 7-9 for massages. Been about 6 times in total.
Hope this helps. Have fun.
