This Airbnb only opened 3 weeks before our stay, therefore there were a few hiccups (the Wi-Fi and the Safe in our room did not work), however the staff was really nice and we eventually got both working on Day 2 and 3.
The unit only had a roll-down mini blind which did not block any light from the bright elevator hallway light (which was perpendicular to our bedroom) or other outside lights/sunlight. Blackout curtains would be required. Apparently other tenants from other units also mentioned having a similar issue to staff.
We would stay at this location again (with curtains :-) .
