We thoroughly enjoyed our stay at CitizenM Times Square. The location was really convenient for both walking and subway access, including a direct subway to the AirTrain (although lots of stairs to carry luggage!). The hotel itself was clean and welcoming, the rooms were very bright and had lots of storage, and were well designed. The shower was good, and all felt very clean. The hotel lobby area was also nice and chill, and they stored our luggage for free.
Only areas for improvement: (1) The lifts are very slow! I think they're operating with 2 rather than 3 atm, but often had to wait up to 3/4 mins for a lift. (2) You can hear some noise from the streets (we were on floor 6). I didn't think this was too bad, especially given the location, but be aware if you're a light sleeper. The noise from the corridor is also quite loud (we were by the lifts). (3) The toilet door could be soundproofed or fitted with a better seal, as it didn't completely close. I was staying with a friend, so we played music to drown out the sounds, but this could definitely be improved by the hotel. (4) You can't link Spotify to the TV, only streaming services.
Overall, would highly recommend and return on a trip to NYC!
