We stayed here with our two elementary-aged children and it was a great spot for us for 5 days in the city. The location is stellar: 2 min walk from the 1 subway line and 5 min walk from the ACE line. Situated on a super quiet street but bordered by two busier streets with access to cabs and tons of restaurants, coffee shops and bodegas. Walking distance to Chelsea Market, Hudson Yards, Empire State Bldg, Union Sq., Madison Sq. Park/Flatiron. I mean, really, it was the best located place I think I've stayed in New York over the 20 years I've been visiting as an adult. So that, alone, is worth it!
The apartment and furnishings are bare bones, but that is not necessarily a bad thing. It's about the size of a hotel suite, plus a large kitchen with all standard appliances. A plus when visiting with kids! Common space furniture is cheap, but the beds were very comfortable! It's not luxurious or particularly cozy, but it was a good home base for a week of exploring. And really, at the end of the day, comfy beds and an excellent location were what mattered for us and this fit the bill!
