We felt welcomed, though couldn't get into the apartment until 4 PM, because it hadn't been cleaned yet, which seemed a little late, especially since we had been traveling since the day before.
I agree with other reviewers that the location of the apartment is superb, a little out of the fray of tourists, but a short walk away from everywhere we wanted to go. There's even a bike rental place 2 doors down!
I would say that the apartment wasn't quite as nice as we envisioned, mainly because it was very dark. I believe that Markus has 4 apartments and this one is on the lowest level. There is only one window in the whole apartment that looks out on a patio that is in the middle of the tall building, so very little light reaches the first floor. The apartment floor was also not as clean as we would have liked.
So, overall good for the location, so-so for the apartment itself.
