“Very ordinary”
Went to Borsenhotel in December for 2 nights.
Although requested one double bed - in typical gerna style, two singles pushed together, with a single duvet each.
Room was a typical 3 star, nothing to write home about, but clean, fairly comfortable and nothing to complain about, except perhaps the walls being rather tin, so could hear the lift, conversations in teh corridor and general comings and going of neighbours.
Was rather overpriced for what it was, but guess that if you visit germany during Christmas Market season, you should expect that!
