First and foremost, John is a wonderful host. He is very responsive and communication is never a problem. He provides a binder full of information about the city and transportation as well as manuals for how to use the appliances in the Kitchenette. Moreover, there are snacks for late time quick meals (if need be).
We did notice a couple nuances during our stay:
1) the lights would dim and light back up automatically. This also goes for the fireplace.
2) there was quite a bit of noise in the mornings. At times, it sounded like the noise was coming from inside the Airbnb. Almost as if someone was banging within the place or on one of the walls connected to the place.
