Unfortunately I really can not recommend Sonder. Even though the location is great and the rooms are somehow pretty we did not spend a great time here.
First and foremost the noise. On weekends and during the week the bars and restaurants in the same building are loud until the middle of the night. The rooms and windows are not sound proof at all. During the night a loud ventilation noise from the outside and in the morning construction work add to this noise problem. They provide ear plugs, but I find that almost offensive, that this is their solution.
In addition it was barley possible to take a shower since the temperature changed from boiling to cold every few seconds.
