The Kelvish is also known as Hotel Happy Stay. It is Not in Aerocity, but is a walkable distance from Aerocity Metro. The hotel and room is clean on the inside, but it is on a busy street. Typical India. Staff was very friendly and helpful. Breakfast was basic, but good. Aerocity hotels are much better but you're going to pay 10 times what Kelvish charges.
Overall, the Kelvish/Happy Stay is a good value. I stayed 2 times for a total of 4 nights and would stay there again.
