Our family of 5 (incl. 2 toddlers) stayed here for almost a week in August.
The apartment is much bigger and better organized than the pictures portray. It was a very spacious 2 bedroom, very clean and well maintained. Pharmacy, grocery store, pizzeria right downstairs/across the street, and plenty of eating options within a block radius. Central Park is also a block away, an easy stroll during the day.
Check-in and checkout was without issue. I arrived very late (1am) and was able to check in with the doorman's help without any problems.
Overall great place if you can catch the owners letting.
