Oyo rooms is very fast growing company. Oyo rooms follow some core premises they are
1.AC
2.spotless Lenin
3.TV
4.free WiFi
They are very strictly following those promises.
I was personally using oyoroom website for hotel bookings.
I was observed that all major cities have Oyo hotels and recently they are spreading to small cities too.. I will suggest you all to use Oyo rooms.
One suggestion is book room by rating of the hotel.
