Sonder was generally a good experience-- the location was walkable to a lot of the main tourist areas, the gym was reasonable well-kept, and the unit, although a bit sparse with basic items (coffeemaker, but no mugs, for example), was totally fine.
However, this listing is quite misleading about its wifi capabilities. I was consistently getting speeds of 0.6mbps, far below an acceptable speed for basic work functions. I contacted Sonder several times hoping to please fix this, but they said there was nothing they could do. In short, fine place to stay so long as you expect to be fully offline.
