It was not minus for us, but it would be nice to arrange tea/coffee making facilities somewhere in common areas (?sauna, breakfast room).
We (11 persons, incl. 3 children) stayed here during Christmas week 2014. Opinions about Pension Katharinenhof in our group were different but I personally evaluated Katharinenhof as very good option for skiing holidays in Kaprun. Very good price/quality relation, good location (~200 m to skibus stop, ~ 300-400 to Billa, a couple of good restaurants in ~100-200 m, not far town center also), clean and spacious enough rooms (no shampoo, take your own!) with balconies, all other facilities you need (ski room, Wi-Fi (could be better), sauna (hairdryers were there, not in the rooms)), appropriate breakfast for Gastehaus (incl. eggs), kind and helpful staff.
