I had a great stay at Kate's and Wes' appartment!
It was clean, comfortable and had everything you need during your visit. There was more than enough space to store my clothes in my room and also my groceries in the fridge and cupboard. I could also use the kitchen to cook, which is absolutely fantastic for everyone who does not want to go out eating in a restaurant everyday (but you could of course also do that ;).
Even for someone, whose geographical orientation is not the best (like mine), everything is incredibly easy and quick to reach. Visiting different districs of NY was very uncomplicated because of the J-train nearby (really just a 5-minute walk).
Last but not least the handling of check-in, check-out and also all questions and needs I had in between could not have been better! Kate and Wes were very kind and and relaxed so that I felt very happy to stay at their place.
