I stayed at Michelle's for 6 nights, when I first arrived in NYC. Michelle's place was everything I needed whilst finding my feet and organising a permanent place to stay.
I really liked the area and public transport was so close! The apartment is also super cute.
When Michelle's home she hangs out in her room most of the time so the lounge really becomes your space. There is a space for your bags and a table and chair so it's easy to get any work done as well. I found the bed/couch perfectly comfortable and the room was pretty quite. Michelle is up around 8.30/9am so expect to be awake by then. The room doesn't get lots of natural light during the day but I'm sure everyone will be out exploring the city anyway!
I think the 6 days I stayed is probably around the longest I'd advice though as you are living in someone else's space. But Michelle was always friendly and the perfect host for me arriving in NYC.
