We enjoyed a lot our stay at Meredith's place. The apartment is well located, just 1 block from the subway and 2 blocks from Madison Square Park. It's really nice, clean, quiet, with enough space for 6 people, and all beds are comfortable. There are plenty of restaurants and places to eat in the area.
We didn't meet Meredith, but a friend of her, Julian, who was helpful and answered quickly to our messages. Check in and out is very easy.
Well, to sum it up, I think the only drawback was that the Shake Shack in Madison Square was closed during our stay and only re-opened the day after we left :-)
