Overall fine apartment. Location and access to transport couldn't be better and the apartment had everything we could have needed, save for a chopping board and an unfortunately cracked mug. However (as mentioned by others) the building is not soundproof at all and the front door to the outside also does not close itself easily nor do you need a special code or key to get into the building so the security doesn't feel entirely up to scratch. In addition we were unfortunately disturbed twice in the morning, once the day after we arrived by a cleaner who thought we should be checking out and who only spoke German, causing an awkward and confusing interaction, but we communicated with the help desk and they replied very quickly and there was no problem after all. We also were woken up at 7:30 one day by building inspectors wanting to see our booking details, which unnerved us a bit. However both these things didn't turn out to be problematic in any way, they just disturbed our peace slightly. Still believe the apartment satisfied our requirements and stay very well.
