The door to the building’s entrance was tricky and did require a bit of maneuvering before the door would unlock - this was the case each time we returned to the building. At first, we also had a hard time opening the apartment door because we weren’t aware that the key extends before use. However, they were helpful in assisting us with that and once the key was extended we had no issue entering the apartment. Once those hiccups were settled, everything went more smoothly. Other than the couch being without a cover (it was eventually replaced with a blanket), their place was clean, the location was convenient and the AC units in every room was a great feature. Thanks for having us!
