Prior to our unit switch (from 312 to 304), we entered the initial unit, which despite being extremely clean absolutely reeked of marijuana. It is frankly unbelievable that whomever cleaned the apartment did not notice the odour and I am quite disappointed that Sonder took no proactive steps to relocate us (given that other comparable units were available). Communication with Sonder was terribly difficult, the chat crashing four total times, having to explain multiple times our predicament (locked out of first unit while our luggage was still inside) because after the unit switch, the previous unit’s door PIN disappeared from the app. Overall, these issues caused us a 1-2 hour delay in checking-in. Despite that, Sonder was unable or unwilling to afford us as a late a check-out as we requested. Not impressed overall and despite an outstanding unit (both units great, despite smell on first unit) due to the complexity of it all, I will not be booking with Sonder again.
