We are a NC family of 4 -- mom, dad, and 2 teenager daughters. There was plenty of space in this apartment. The first thing we noticed was that the place was immaculately clean. Our contact, Mila, was an absolute delight. She was easy to deal with and met us out front when our taxi pulled up. Mila showed us around the apartment and answered any questions. She then went, in our opinion, the second mile by giving us a walking tour of the neighborhood. She pointed out the various groceries and markets, and the many restaurants (both eat-in and take-away). One of the things we liked about the neighborhood was the variety of eating establishments. As we walked around, we felt very safe. The subway (B and Q take you right into Manhattan) stop is a brief walk just around the corner and up the street...maybe 4 or 5 minutes. It takes about 35-40 minutes to get to Times Square (from the time you leave the apt until you get to the Times Sq stop).
Our only negatives would be: After sleeping on sleep number beds at home we found the beds to be a bit uncomfortable because of the thin mattresses. Also, due to some post Hurricane Sandy plumbing issues they asked that all used toilet tissue be placed in a trash can with a lid (provided). Although the toilets seem to flush just fine, we complied and took the trash out twice a day -- once in the morning when we left, and once at night before going to bed. Not an ideal bathroom situation, but not unbearable.
Overall, if you are looking for a convenient, clean, relatively comfortable, inexpensive place to stay while you do the tourist thing, this is a great place to consider.
