Rooms are very small with limited storage/clothes organization space. It might be okay if you’re traveling light and have 1 luggage but not more. Bathroom is small, but more importantly shower is hard to use and show spouts were moldy. The room turnover service did change the bedsheets within a day, but they did not replace the wet that were towels used. Property has a rooftop bar and a speak easy that has an adjacent entry to the main door, it was okay.

Mixed experience

The property is quite tired. I had to move room because of a problem with broken fittings. Thankfully the staff upgraded my room, which was better. I'm not sure I'd stay again.

We arrive to our room and noticed it wasn’t the correct room. We tried to find the receptionist but they had gone on a break. Over the last hour I went downstairs to check if the receptionist returned with no luck. In the meantime I am using the chat feature on the app. No help whatsoever. Poor customer service. They had me on hold for over an hour, only to say there were no king size beds available. I contacted Expedia for some help to obtain a refund and the hotel denied the refund and because of expedias refund policy, I couldn’t get my money back. We left the hotel and stayed elsewhere and Expedia continued to attempt to get our refund. I finally got through the hotel and they offered us a refund for the days we did not stay and only charged us for one night, but they also charged us for the upgraded room and when I asked about that they never responded. Do not stay here. Absolutely terrible experience. Uncomfortable bed and uncomfortable space for that queen room I was in.

Enjoyed my Biz trip

Great location! Restaurants everywhere. The only thing I missed having was a desk in the room to take phone calls. It could also have better lighting but the windows are huge and let in natural light. Loved my stay! The staff was also super friendly.

The room was well kept and the toiletries were complete. The shower space is a little too small though but there was a lot of shampoo, conditioner and shower gel available. The dispenser pump of the shampoo was defective though. The staff were accommodating and quickly responded to requests for assistance such as cleaning arrangements. The online check-in and check-out experience was seamless and convenient. Generally, our experience was quite good.

My husband and I really enjoyed staying here. The location was pretty good for getting around Manhattan with a subway station 2 blocks away. And the room and bathroom were much larger than other hotels we had looked at for a similar price. They were prompt in their response over the app when I needed more towels for the room, and it was great that they provided a white noise machine and earplugs to help cancel out outside noise. Will definitely be looking into other Sonder properties in the future.

I personally like that there’s no concierge checking in checking out dealing with long lines before you go and when you arrive and the convenience of it all. If you’re looking for a posh hip place to say this isn’t it but this place is clean and I love the flat iron district area a lot of convenient amenities everywhere
