When arriving at the apartment the window blinds was defect which was terrible since this made the sun shine into the unit all day, and during night we had no protection regarding outside view into the bedroom. In addition to this there was no air conditioning even if this was listed as a facility for the apartment.
After 7 days nothing had been done to solve the problems, and in agreement with the host, we moved out of the unit.
We contacted the Airbnb Customer Support and they helped us get a 100% refund for the remaining days. Very pleased with the support from the Customer Support Center.
