I have been to Obsession a few times over the years on my visits to HK. The staff are on the mature side, which is a plus in terms of strength and experience. The rooms are comfortable (maybe on the kitschy side) with private showers. Paco was my masseur a couple of times. Friendly guy, not talkative, good masseur. Nice touch: no pressure for a tip. They take care of that when you pay afterward.

Location is great. When I got there, someone else was sitting in the lobby and the manager could not stop giggling. He ushered me in to a treatment room without even discussing anything. He impatiently explained the treatments on offer. Also mentioned clearly: Professional service only. But at that point I was not interested in this anymore. If you want to learn how to make a customer feel bad, go there.

Bang in the middle of the bustling Tsim Sha Shui district, easy to find. Initially, when you call them to book an appointment, the response can put you off. But it is probably to do with the guy on the phone being not well versed in English. So, you can ignore that and land up. The price for a 90 min massage is approx 400 HKD, very reasonable. And, the tips can be none to whatever you want, they don't ask. That's the best part about this place. No haggling or bargaining by the masseurs for tips and for "extras". The place and money stuff is very straight (sorry, bad pun) forward. I have been to other places in Tsim Sha Tsui and always found masseurs trying to extract tips and bargaining. So, this place is excellent. The masseurs are older (which I prefer). I went twice and found the same guy. Very professional, pleasant and goes straight for the job. Good massage technique and very good service orientation. The place itself is clean and OK. Absolutely recommended.
