Rosa's place is in the heart of Greenpoint, just one block away from the Brooklyn Expo Center. It's a basic room in an older apartment building. If you just want a simple space that's not fancy and will spend most of your time out and about, you can't go wrong. Rosa is extremely nice and helpful. She told me about a wonderful Japanese restaurant (Zenkichi) and gave me advice about where to walk around Greenpoint and Williamsburg.
