The apartment is rented by Komodo Apartments, a short-term apartment rental company. The apartment itself was spartan but fine, though it included notices all over the kitchen that if anything was done incorrectly (recycling, dishes) they would charge your credit card. There was an additional city tax which had to be paid in cash at check in. There were not enough towels or sheets in the apartment when we arrived, though the person working at the front desk brought up towels an hour later.
The most annoying part of this stay was not having directions to the place - the address listed is just for the city of trento, not the actual place. It's 15 minutes walking from old town and 25 from the train station. They never sent me an address, though we did figure it out eventually from the image of the zoomed-in map on the airbnb app. The "Paolo" that we booked through never responded.
