Fact: it is one hour walking from the city center.
If you book the 10th floor the view may make up for the not-so-good location. But although we did so, upon arrival we were told it was occupied (!) and we had to stay on the 4th floor. So we had to cancel our reservation when we were already there!
Also if you want a "single" apartment, you might get a bit surprised. What we saw was basically two independent rooms with shared bathroom and kitchen in another hall, something like one sees in student dormitories.
