The location was the highlight for me. It was close to the river, which has excellent paths for walking. There was a bakery around the corner, and several good restaurants within ten minutes. Also, many of the tours and tourist sites are within a 40 (or fewer) minute walk.
Check in was easy, as Alex left excellent instructions.
There was lots of room in the apartment, but the shower was in the kitchen, not in the bathroom. That didn't bother me, as I was by myself. It might be problematic for a bigger group. There was a slight whiff of mold in the shower. Also, the big room was fairly dark, as it had one window. As I didn't spend much time in the apartment, it didn't bother me. But in winter it might feel too dark inside.
I would rent this apartment during the summer and fall. The location is that outstanding.
