Hello thank you for your feedback.
Yes the building is from 1960 and so it had an older touch, but i already spoke with the real estate management and the told me that there are already plans to renovate the entry and hallway area to look fresh and new again. This will happen in the next few weeks.
I already fixed it yesterday. Cause of the apartment and the entry door is completely new renovated last summer it looks like the temperature moved a bit the fitment of the door lock bolds. I rearranged the door yesterday and the lock works now smooth and fine again.
yes there was somewhere a technically problem, which will be fixed. I build in a Toshiba air condition for all rooms and it also just 1 year old. Normally this should not happen, but yah, technical things can break and i am sorry about that it happen in your time of stay.
I always try to give my guests a perfect stay... next time this things will be fixed. I promise it!
