nice apartment with good price/performance-ratio. I would book it again.
If you want to walk to the old town by foot, it takes around 30 Minutes, but the tram is not even 10 minutes away if you want it a bit more comfortable.
There is also a small supermarket below the apartment which is also helpful to buy some stuff if you want to use the kitchen and cook on your own (just easy stuff like scrambled eggs or sth.)
