Let me summarize Gurgaon spa scene having been a regular visitor since 2015.
1. MG Road and Golf Course are dens for moderate to expensive Spas. All the malls have plenty of spas and new ones keep coming up.
Most of the spas have options for both NE and NI. Showers have hot water coming. Towels are tried to be cleanly maintained though they smell of oil and hygiene is average. Counter charges vary from INR 1,500 - 3,000 and therapist charges anywhere from 1,500 - 5,000 depending on the services. I generally keep my own towel and that suffice for quality control.
NI girls typically offer both HJ and B2B. They very rarely do DFK, sometimes allow fingering after second visit onwards, BJ is rare too. NE girls offer HJ, B2B. DFK, FS and BJ are available after 2nd visit in most cases. Some of the really pretty NE therapists (almost model like) I have met however are very particular about no B2B, even after 4-5 visits.
2. Places like Gold Souk, Hong Kong Bazar, Sohna road malls offer cheaper places with counter rates between INR 800-1,500 and the therapist charges anywhere from 800-2,500 depending on the services. Poorly maintained towels, showers may not have hot water coming. If you are stickler for quality, very difficult to be happy in them.
3. Five Stars and Expensive spas like Swasdee - counter charges vary from INR 3,000 - 6,000. Extras are available rarely though I have been able to get at 1-2 places. Hygiene levels are excellent and price is worth the premium if we can get some guaranteed good names here. Heard from someone that Westin in Sohna has some excellent Ayurvedic therapists - not confirmed though. This is my most preferred category, if someone can PM me some references would be happy to share mine too.
4. In-calls and Out-calls - No experience in In-calls. However have enjoyed some out-calls in hotels in Delhi and Mumbai both and experience has been mixed. Very rarely will they send the same girl as advertised in pictures. For real model type or models, the asking price is very high - Inr 2lakh+. In some moments of madness, I have enjoyed two of these. Experience is worth it, but be prepare to shell out an amount for a night that would have you covered through other means for at least a year.
5. Tantra Massage - I have enjoyed Tantra Massage in Gurgaon, Malaysia, Belgium, and Thailand. In India, there is only one service provider and acts very pricey. Some Delhi spas advertise their services as Tantra (aka Lotus Spa in GK II), but dont trust them at all. Tantra is something that you have to experience to believe it. Amongst every other option I would choose it any day of the year.
Please do share your wonderful experiences too and do PM me if you need any specific information. Would be happy to have some direct references for in-calls/ Tantra massages. There is real dearth of quality out there so it would be really helpful for us to share as much information as possible.
