This is a fantastic apartment in Manhattan for anyone - but especially for a family with young children. We were traveling with two kids under age 8, and the layout of the space was perfect for us, with a very large master bedroom with king bed and the second bedroom with a small set of bunk beds and lots of books and toys for small people. There is a bathtub and high chair as well.
The location is ideal. The apartment is very quiet and removed from the street, but you have easy access to amenities and transportation. We easily walked to Central Park, the Met, and a little further to the Museum of Natural History. The Q train (~3 blocks away) goes directly to Times Square and Broadway in just a few stops. Many restaurants and shops in the immediate vicinity, too.
Finally, Helo was extremely welcoming, considerate, and quick to respond to every question we had. We really felt like she went out of her way to make our stay comfortable and convenient. Thanks, Helo, for sharing your home with us.
