Choose a location close to market and your college.For students enrolling in Hansraj, KMC, Hindu, Stephens or Ramjas,locations like Malka Ganj and Kamla Nagar are ideal. For DRC, SRCC and Miranda,you can go for Roop Nagar,Shakti Nagar,Vijay Nagar and Hudson Lane.
Make sure that the electricity charges are included in your rent. Exclusion of the same leads to rift between roomies when bills start rolling in (as one might consume more electricity than the other). Also see if the pg has¬†an installed washing machine,fridge on each floor,induction/stove/microwave and water purifier.
Being a fresher it is important that you opt for a dual sharing room as it not only help you make friends easily but also gives to you a family away from home in a new city.Your roomie will be there for you in hard times even if you two don’t make best of friends.
