We just got back from a fantastic one week stay in Jenni's home. It's a great place, with an awesome Shabby chic with an edge feel in its decor. We were pleasantly surprised by how incredibly kid friendly it was - the backyard was a boys paradise and there is a chalk board wall in the kitchen and plenty of games and toys. The downstairs kitchen/dining/living plan is open and plenty of space for our 3 kids and us for the week. The only negative I would say is the house is old and noisy. You can hear every footstep, etc. I'm use to that from living in old homes before, but when my husband needed to leave for work at 6am he woke the whole house with him. Also there is no coffee machine or toaster, but you are 3mins walk from a NY bagel place where you can get both.
Overall it was an exceptional home away from home. Great location, close to everything you will need for a great NYC holiday.
