Before arriving I was given a link to an app for checkin and unlocking the doors. Great idea and half works - the apartment door unlocked fine, but the main building door didn't work and as I arrived late the office wasn't open. Thankfully some other people were entering the building at the same time so i was able to enter and use my phone to enter the apartment and then get the keys that were left. Very nice space, good location and some nice touches provided, such as a small breakfast box and cleaning kit.
