We spent 5 nights at Santas place. The flat is small, but it was ok for four young adults. Location is superb, historical center is close by. Santa gave us video tutorial how to get in so no problem here. Everything was clean and nice.
What could be better, was inside temperature. I know, it's not Santas fault, because there is central heating system, which is controled by the city. The smaller room was ok (if you dont forget close door), but the bigger one was quite cold. I just needed to mention this.
