We (four adults) enjoyed a lovely stay at Lilian's apartment. It was clean, bright, and cheerful, and just as charming as the pictures. I've visited NY before and this is the first time that I've ever had more space than we needed or used.
The space was easy-to-navigate with helpful and charming labels everywhere, for everything from the fire extinguisher to the recycling. I definitely can't guarantee that the people you travel with will make you coffee before you wake up like mine did, but I am sure that no matter how tired you are first-thing you'll be able to find the clearly-labeled ground coffee along with coffeemaker instructions.
I also strongly recommend following the local recommendations in the apartment guide. We ate at two places that she described, and both were delicious -- some of the best food we had while in NY!
Lilian's place exceeded my expectations in every way. I was sorry to leave, and would absolutely go back.
