Both the places I stayed in had an overpowering disgusting stale cigarette odour in them. I could smell the same odour on the Sonder staff. All of my clothing had absorbed the odour and needed to be professionally cleaned when I returned home. I was ill from the odour as my allergies were triggered also caused headaches. A female Sonder named Emily advised that she would assist with my concerns and never returned. I was unable to get assistance from anyone at Sonder through texts or phone calls. I would discourage everyone from using Sonder. Extremely disrespectful and useless customer service.
