We, a family of 5 people, stayed for roughly 10 days at William & Angela's apartment. It was a very pleasant stay. I would say a group of up to 5 is a perfect size considering the size of the apartment. The apartment was very clean and has a superb connection to Manhattan. William answers very quickly to every question. He also had some nice tips on hand, whether it was about a nice place to dine, sights or train routes. My family and I felt very welcome and we can only recommend this apartment and these hosts.
