The accommodation is located in very convenient place in San Francisco. When first arrived, I noticed that there were used bed sheets in the closet, and half full garbage bin with tissues and airline luggage tags from the previous tenants. Not a big deal to be honest, but it seemed that the cleaners did not fully perform their services (one-time service, $90+). I woke up the second night from the loud noise from the shower, with skin irritation from the bed sheets. Knowing that I could not stay focus for my trip, I decided to move out.
I was hoping to reach an agreement with the host for an early cancellation, perhaps he was just unlucky with the cleaners. However, the host insisted to charge me for the 21 / 24 night that I will not be staying at his place, with the response "I've gone above and beyond to accommodate your even unrealistic expectations". Thankfully the great AirBnB service support eventually was able to arrange early cancellation for this accommodation.
