We have a big, bright room open for a guest in our 3 bedroom apartment. It's located on the top floor and has direct access to the rooftop as well as a balcony. The apartment is located in East Williamsburg and is surrounded by great bars and restaurants. The nearby trains are L (Graham) which is 15 minutes from Union Square in Manhattan.
We're two people in our mid 20's living here, both working full time and out for most of the time.
The bedroom is well sized, with great natural light. The cupboards and drawers will be filled with the owners clothes and personal items, so there will be minimal use of these cupboards and drawers for guests in the bedroom.
You'll share a bathroom with one of us. You have full access to the apartment, kitchen, balcony, rooftop etc.
