Sonder was a great location for a great price. The room was small but perfect for 2 people. It is not in the Flatiron Building but it’s in the Flatiron area. Location was safe and close to subway stations. It was a bit noisy but that’s just NYC, we’re from Tennessee so not used to the noise. “The Smith” restaurant that’s very close is 10/10. The TV is chrome cast so make sure you bring your laptop if you want to watch TV. Overall great stay!!
