Amazing location, beautiful apartment, thoughtful hosts. Best airbnb I've stayed at in terms of experience - these hosts have thought of everything. The apartment is so well organized/designed and it's stocked with many thoughtful amenities.
There's a lot of mention in these reviews about noise from the subway - I wouldn't worry about this at all unless you're very sensitive to noise. It was a low rumble at most and kind of calming, like white noise.
