I was really disappointed in my stay at the Sonder in Back Back. While the exterior of the building is very charming and the neighbourhood is lovely, the unit I stayed it was in the basement, with only partial windows that were at and below sidewalk level. During my stay I encountered what may be bed bugs, collecting over 10 small brown beetles from the bed, curtains, carpet, and wall. As the hotel does not have staff onsite at all times, I brought this to the attention of Sonder customer service following my stay and was not given a refund. Moreover, I received two overcharges in excess of $1,500 and had to contact customer service twice to get this resolved. I am extremely disappointed and will not be staying with Sonder again.
