Very nice appartment. High quality equipment. Kitchen is lacking some key useful features features like microwave or a dishwasher.
Central location, however not everybody may feel comfortable with the neighborhood.
Mani issue: during our stay, the rooms were very very cold and the heating system was strong but far from sufficient to heat the rooms. issue is lack of isolation of sealings or extremely high sealings. all this might be an advantage in summer time, but a problem in winter. we even mis-used hair dryers to get some temp in bathrooms in the morning.
All major sights are really arround the corner, including some small shops.
