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.

Liked: Cleanliness
Excellent room, very large with tons of windows. Unbeatable location. Room condition was so-so. Note to Sonder: just because there is a microwave doesn't mean its a kitchen lol. No stove or hot plate, no toaster, 1 mug for 2 people etc. Room is fantastic but the property could try a little harder. We had to request a shower curtain ...

OSCAR

Disliked: Cleanliness, communication
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.

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 expected a normal trip to New York as we typically stay at 4 star hotels. We were disappointed to say the least. Our bathroom was small, leave the door open to use the toilet, the shower could use a good cleaning.

I had a wonderful stay! Check in/out was efficient, with the option to Room was clean and larger than most you would find in New York. I d I had a minor maintenance issue at the start but the Sonder team was very quick in responding and solving it.

Unique location if you love vibrant street life. Easy to walk towards Empire or other way to Washington park. You basically rent a room with no other hotel facilities. Virtual key chain did not work properly which was quite annoying. Room windows were dirty that gave uncomfortable feeling. The staff was not always present or came late.
