This was my family's first trip (kids ages 8 and 9) to New York and we chose the Box House based upon reviews and price. I couldn't believe the value! It's a beautiful, funky hotel with everything you need for your visit. Extremely quiet during the week. You're just a hop skip from the 7 train and you can get anywhere from there. You're a block away from a grocery store that has anything you need.
My only warning is if you like total quiet, don't stay during the weekend while they do weddings. We were on the ground floor and the music from the rooftop was very loud, making it difficult to sleep. (Knowing that I'm sensitive to noises, I brought earplugs and that worked fine.) The rest of the week, it was as silent as could be! We will definitely be back for another visit and I'll absolutely recommend this spot to friends and family.
