I know that the construction site is mentioned in other comments and I guess it depends on the days but we were unlucky with the work starting at 7am to a loud extent (nerve wrecking metal grinding) right below the bedroom window. Hopefully, Katarina was very comprehensive and responsive so we did manage to find a workable solution to enjoy our stay after all. The service was fast, easy going and resourceful. There were no conflicts of any kind.
The apartment is clean and equiped for corporate use with basic furniture so don't expect a romantic place but rather a functional one, spacious and nicely located. There were a few sign of wear out due to the previous rentals and Katarina was not aware of them since she had been abroad for a while, but she promised to fix the lamps that were not working and other degradations that we were not expecting considering the price and the pictures provided.
One thing is certain is that Katarina cares about the well being of her guests and she made all the necessary efforts to provide us with the accommodation quality that we were expecting. That was much appreciated.
