Kaya Preet Vihar sucks. They made me wait for half an hour for an aqua radiance service and then finished the service in 20 mins. Charge- 2000 Rs. On the website, they mention it as a one hour service. They told me it is for 45 mins. I noticed the start and the end time and it was exactly 20 mins. I ll never go back there again..Noida sector 18 is far better
