We have recently returned from a trip to Austria, where we spent 4 nts in Zell-Am-See. We stayed at Haus Ashling, Nikolaus Gassner Promenade. This is a B&B which is run by an Irish couple. The B&B is fantastic, can't recommend it highly enough. It is actually located about a 5 minutes walk from centre of Zell, up a steep drive way. The City Express ski lift runs directly past the door of the B&B so if you were skiing you could literally ski to the door. The rooms are spacious and clean, as are the bathrooms. There were just the 2 of us staying in our room, but there was actually beds for upto 5 people. We had a room at the front of the house with a balcony, with fantastic views over Lake Zell and the surrounding area.
Breakfast was continental style, but perfectly fine to set you up for the day. The hosts, Eugene and Margaret, although only Eugene was there during our stay were very friendly and helpful. His hospitality could not be faulted.
This isn't a well advertised B&B, I found the link for it through Hostel World website and then contacted the B&B direct via email. We were charged 35 euros each a nt (would have been 30 if we had a room without a balcony).
Highly recommend this place!
