Although the apartment was as advertised, and price and location were good, an unknown man entered our apartment in the middle of the night. This person used our personalized access code to enter, and left the apartment when confronted. According to the establishment the only people with access to the codes would have been a maintenance person or housekeeper. We find this totally unacceptable and unexpected. It is also the reason we will not stay at this establishment again, or recommend it.
