Highly recommended. I lived in NYC for a while, and when traveling back for a visit, I was very selective about location and having A/C in the room since we were there in July.
Mary’s place is within a couple of blocks to the 2, 3, B, and Q trains. They are short rides into Manhattan, and direct or with a single transfer you can get just about anywhere. Also within a couple minute’s walk from Mary’s: Prospect Park, cafes, restaurants, bars, bagel shop, and bodegas. The neighborhood is quiet and safe.
Mary is a wonderful host. We thoroughly enjoyed hanging out and talking with her when we crossed paths coming or going. If you want inside tips on the live jazz happenings while you’re in town, she’s the best source.
