We had a great stay! Would stay again in a heartbeat.
The apartment was very spacious, well laid out, with all the amenities, very clean, and super quiet at night, which is quite remarkable in Manhattan!
The check-in / check out process was super easy with Sonder, and we were able to leave our bags in storage the last day after check out and the staff was very efficient and courteous.
The location was great with access to public transportation, restaurants, and minutes from the East River and Battery Park for nice evening walks.
The only reason I didn't give 5 stars is that Sonder notified us only at check in regarding construction happening next door, with noise starting at 7am. I wish we'd have that information at booking time to make an informed decision about our stay. That being said, the Sonder team was very responsive and provided a noise machine. Also our unit was on a lower floor, but I bet that for a higher floor unit it wouldn't have been that noisy. Honestly overall it was pretty quiet by Manhattan standards.
One last thing that may be good to know is that for one of the 2 bedrooms, the door had windows like for a den. So if your party needs privacy in all bedrooms, you might want to ask ahead of time if the bedrooms have real doors.
