Very functional. The combination lock on the front door is exactly where a skeleton key would go to unlock a door - but I couldn't see the lock since I arrived at night in the dark. You'll need a flashlight. Quite clean inside once you actually get into the apartments and out of the hallways. If you need an extra mattress ask for it to be delivered to your room in advance with towels and linens. Never met the host, but he answered my questions promptly. The sheets were soft and clean. I appreciated the A/C and fan.
