Sanders Regent - Cute 1-bdr Apt Next to Magasin

I experienced that the key did not work on the second door. There were 3 doors: 1) Gate from street 2) Door to building and stairway 3) Door into apartment on 2nd floor The key worked on the gate (1). The key dit not work on the door to the building (2) I was stading outside till 10 p.m. The key worked on the door to the apartment. I tried calling - I just got an answer machine I tried writing emails but got no response. Sanders needs to change the lock on the door. Sanders needs to make sure there is a phone number to call outside of opening hours. My experience was not satisfactory, considering the amount of money I paid for this accommodation. Thank you.
