The apartment itself was fine, but a few basic (though important) aspects were missing.
1) Not enough toilet paper. I've never encountered this. One bathroom had a full roll, and one mostly used roll.
2) The host wouldn’t let us leave our bags for 30 minutes to an hour after the strict checkout time of 11am. He only offered that we could put them in a luggage storage service quite a ways away.
While he's certainly under no obligation to let us store our bags inside the apartment before flying out, it's an industry standard. I've travelled all over America, Europe, and Asia, and this is the first time I've encountered this situation in either a hotel or AirBnB.
Suggestions for travelers:
Unless your flight/train just so happens to leave a soon after checkout, I'd suggest looking elsewhere.
If you do decide to stay here, make sure to bring extra toilet paper.
