We traveled to New York with our one year old and were delighted with how baby friendly the studio apartment was.
It is below street level (basement) so it was easy to access with baby and stroller with few stairs leading down to it.
The apartment was equipped with a crib and high chair which made our life a lot easier and made it feel a lot more homely than some of the hotels we've stayed in.
The kitchen also made it easy to prepare baby meals etc.
The apartment is in a brilliant location and Karen and Paul are lovely.
