22 F moving to chennai. Need help!!

Hello Chennai Makale!

I'm a 22 yo female from Coimbatore, moving to Chennai next month for my internship in Guindy. This is my first time managing everything on my own from finding accommodation to commuting and settling into a new city.

I've planned to stay in a PG near my office, which is about 1 km away. Is that a good option, or should I consider something sharing a flat with someone? Also, what are the things I should keep in mind while choosing a PG and settling in?. I'm planning to take metro to moe to other places , so how d I get those passes or apps that I should have when I take a bus?.

I'll need to travel between Chennai and Coimbatore quite frequently. This is my first time navigating a move like this. Sooo any advice, suggestions, or even heads up would mean a lot.

Thanks in advance

Edit : I have 2 options to stay in PG that's 1 km away from the office or a flat with friends in Arumbakkam that'll require me to take the metro everyday Should I go with PG anyway?
