The apartment is really nicely located in the historic city centre, with all Trento sites in short walking distance. Our host was very welcoming and even though we didn't share a common language we managed to communicate with Google Translate without problems. Kitchen and bathroom were well equipped.
We had two issues though. The nearest parking is a about 10 minutes walk away and costs 25 € per day. Cheaper ones exist but are farther away. Also, on Thursdays there is a market and your car (like ours) will be towed away if you park near there.
The other thing was that it was so hot in July that we had to open the windows in the night (since there is no airconditioning). But the street is really noisy until about midnight. Providing one or two more ventilators would be useful. But this summer was unusually hot, so when it's cooler this would not be an issue.
