Need PG in Sector-21

Hi guys, I’m moving to Gurgaon in Jan. I’m looking for Coliv/Boys Pg in Sector 21. My office is in Candor techspace. This is the first time I’m moving away from my hometown. So good hygiene and decent food are my priorities. My budget is below 20k for accommodation. Looking for Single/Double sharing rooms. Pls suggest some PGs. Also do let me know what are the things I should consider while searching pg and what I should beware of.
