oyorooms.com offers an App through google search. whereon it shows link of "50% off on App". But in actual it doesn’t happens. The Customer Care Executive will just offer you Rs.300/- discount or will ask for a code; which in fact does not exist anywhere while downloading the app.
Moreover at the time of giving information the executive will tell you "If you check out before Check out time, you will be liable to get the discount of 20% of the amount paid for a day". Actually It doesn’t. This is my recent experience with Hotel Bhooshan, which is in Revenue Colony, Pune.
