The flat has a pretty good location, we were driving and there was a parking free of charge which was of use. We also had a great restaurant very close. And it was very easy to get in the city center by foot even with our kids (15 to 20 minutes walk).
However, the main issue we had was the noise. The wall of the building are very thin and we could hear every single movement of our neighbors. Unfortunately we had late birds neighbors that would male noise late in the night (2-3 am) and we had other neighbors that were on the other side early birds that were up around 8 am and we would also hear them.
