The location could not been better, the apartment is very good for a short stay. The apartment is located in the middle of the historical city center, in a quiet side street of the most busiest streets.
Minor downsides during our stay were the unmade (small) bed with no bedding around to make the bed ourselves, and the bathroom. You can expect the complete bathroom to get wet due to the shower setup, and during our stay the showerhead fell off during a shower, so we couldn't shower anymore the last night.
Still, when the latter will be fixed, it is a recommendable apartment. We enjoyed our stay!
