Our stay at Anna's was just wonderful. We had a family of 5 staying in the apartment and it was quite spacious for us all. The two bedrooms were very comfortable and the couch was certainly big enough for our kids to sleep on... and would be fine for smaller adults as well. Kitchen was large, with everything you need, plus a coffee grinder!
Getting to the subway is easy, it's a 10min walk, and up on Cortelyou Road there are some great cafes and restaurants. Anna provides some guidebooks and maps which are helpful, plus the internet is solid. I'd certainly stay there again, it's great value for NYC... Anna is so helpful, it was all excellent.
