Key is the safety issue that is the door(s). Three doors with two keys that take extensive amounts of time to open, close, and lock (the outer key is very finicky) -- even after you figure it out (no instructions provided at time of check-in). So you are standing in an alleyway for an extended period unlocking, opening, closing and locking yourself in. Not recommended for those concerned about safety (even though Bologna itself is a relatively safe city). Renters should know the unit faces on an alleyway where an osteria has outdoor tables and runs to 3 am, leading to extensive late-night noise many nights. The unit was not clean upon check-in including bloodstains on the extra quilt, the bathroom sink wasn't working (fixed with a phone call), and there were no written instructions about anything in the unit -- washer, a/c, trash/recyclables, stove. The kitchen wasn't well equipped, and it does not appear that much thought/oversight has gone into the unit, how it is presented/equipped.
