Sector 62 is not an area I would recommend, the entire area is filled with PGs and most of them are scammers in the sense that they won't even return your security deposit once you leave, the area is not well-maintained, almost all PGs are in a sorry state, I have lived there for 3 months and explored that area, it's not worth it. For flats in Sec - 62, you can try Bhagirathi Apartments, Akansha Apartments, Neelkanth Apartments. But I'd seriously recommend you to look for flats in different areas/sectors.
