Cannot recommend this place enough!! Had some doubts when booking because of some reviews I read but those were immediately dispelled after I checked in. The Sonder team was very easy to get a hold of and responded in a timely manner. They addressed all my concerns prior to checking in, which I appreciated especially with how challenging travel has become during the pandemic. As I was arriving from Singapore, I wanted to check-in early but the room I was allocated was not ready. However, the front desk was so kind and found me one that was, allowing me to settle in earlier than expected.
The room itself was spacious for NYC standards, especially in the area where this Sonder is located. I found it to be very comfortable, clean, and thoughtful in terms of amenities - coffee machine, refillable water bottles, portable charging dock by the bed, Davines toiletries (shampoo, conditioner, body wash), etc.
I chose this Sonder for the location and while I did not take the subway (mostly walked or took Uber), it is very convenient. I used to live in Midtown East so am very familiar with the area. But for anyone who would be visiting for the first time, I do think this location is pretty central and accessible to popular NYC spots. Honestly, the location is unbeatable with Central Park around the corner!

It was also very easy to manage my stay thought the Sonder app, such as when I requested a cleaning and had questions about the Chromecast (which worked well once set-up!). I liked that they had all the information about the Sonder as well as recommendations for where to eat nearby.
I really commend the staff as they truly care about the guests' stay and were very proactive in ensuring that any issues were resolved as soon as possible. There was an afternoon when the wifi was down and they messaged all the guests as soon it was fixed. While they warned about construction nearby, I actually didn't hear a sound! My check-out process was seamless too, and they helped me with my bags.
In summary, do stay here if you have a chance to! You won't be disappointed :)
