The apartment was clean and it's located in the middle of the city and close to historical sites (such as the Central Market or the Cathedral). The building is quite old and there's no central heating (there were small individual electric heaters). The street itself is quiet and traffic free but because of the single-pane windows you'll still hear noises from people outside and traffic in the neighborhood.
I can't say the kitchen was well equipped. For instance, an electric or stovetop water kettle would have been nice to make tea or coffee (there is a microwave though, and a mokka pot, but that brews only one cup of coffee). Also, there was no cutting board, and the cooking pots had no lids. A major reason why people choose an apartment over a hotel is so that they can prepare there own food. But these are minor downsides that can easily be solved, and I've made some suggestions to the host.
