Sublet or Place to Stay during Summer Internship

Hi,
my name is Tobias and I’m looking for a place to stay during my upcoming summer internship in NYC from June to September. I am from Munich, Germany but have stayed in the US and Canada before. In my free time, I like to be outside running or cycling or exploring the local bars and foods. I am eager to get together, but also respect everyone's personal space. Since my internship is full-time, I will spend most of the time at the office on weekdays. I'm tidy, quiet, and don't smoke.

Looking for furnished rooms in shared flats or studio apartments in Manhattan (see areas listed above).

Thank you for your reply!

Tobias
