My kids and I stayed at the Blue Penthouse when my daughter was moving to Columbia. What I loved most about it was the location being so close to the B, C subway lines at 135th St. We could walk to Columbia in ~20min and get anywhere we wanted to go in the city via the subway. The penthouse apartment was very spacious and we had 3 adults staying there for a time. The only caveat in this situation is the bathroom is in the bedroom, so my kids would have to come into the bedroom to use the bathroom. It was totally fine for us - but may be a consideration for others. The apartment is clean, quiet, stocked with everything we needed, wonderfully air conditioned, and Yosef (and his awesomely friendly dog) were great hosts. I will come back to stay when I visit my daughter at school - no doubt.
