Best people running the show, they were kind and accommodating. Even when there was maintenance on a floor, they found a way to get me back to a compromised room size. I will be back to this Sonder Flatiron location! Thank you!

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 ...

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.

The hotel is located in an amazing and safe area. Unfortunately the check in process is not great. The room is small as expected but you could barely get into the bathroom with how the toilet is placed and the door doesn't swing open all the way. The floor in the bathroom was dirty, the shower drain had hair in it, the ceiling vent had dust on it that flew down when you turned it on and the bathroom vanity cabinet was broken and beat up. The room space is decent, but the bedding is really bad. It's a synthetic fiber comforter that has been washed so much that the fibers just clump into certain areas and should be thrown out. Definitely not what I expected.

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.

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.

Unclean and very noisy

I experienced several issues with my room that impacted my stay. The noise level was quite high and earplugs weren't sufficient to block it out. The bathroom had mold and felt dirty overall. The walls throughout the room need attention - the paint is chipping and requires a fresh coat. I was surprised to find no water available in my room, not even for the coffee machine. There wasn't a water fountain anywhere in the hotel, and when I asked about purchasing water, I was directed to the closest CVS. The windows were very dirty, and I noticed dust accumulated in every corner of the room. I do want to emphasize that the location is great, and the reception staff were absolutely lovely - the lady who checked me in was the kindest and most helpful person. This feedback is purely about the property condition, not the service. My main concern is that I paid a high rate per night, which set much higher expectations for the room quality. At this price point, I felt disappointed with what I received and honestly feel a bit ripped off. Had I paid a cheaper rate, I wouldn't have had the same level of concerns about these maintenance issues.​​​​​​​​​​​​​​​​

the staff were very nice but check is was a hassle; codes did not work; when i went to request room cleaning first morning on line at 7am and it would not work they told me it had to be requested at check in; no one told me that; coffee machine spewed grinds, show dispenser pumps broken and with all the hard surface the room next door was too loud.

I liked the location, I liked my room, the bed was great and so were the pillows. The shower experience was 5 star. However, not so clean! Hair here and there, the place could use a good wipe down! I wasn't there long so it wasn't much of any issue. It's as if the hired cleaners have not been trained how to properly clean a room. Also, the room is stuffy. AC resolved the problem for me, and it was 45 degrees outside and raining. It would probably be terrible if one needed the heater instead of the AC.
