Our stay was very pleasant and we had no problem at all. Checking in an out were completely automatic. We phoned them on our arrival day for an early check-in, which they were quick to answer and accommodate.
The location is very good and central, and although the building looked old on the outside, it was warm and modern on the inside. We saw a review from another guest saying there was noise from the bar below, but we had no noise issues whatsoever.
The apartment was clean and contained all the essentials.
