We stayed at this great place for 3 nights in early October 2015. We loved the location and the rooms are very large and super clean. The hosts are very friendly and helpful. It is a quick walk into the old Market part of town, and the bus stops very close to the B&B so you don't have to walk through town to get to the bus stop by the TI. The hosts can do laundry for you at an extremely reasonable price. Our room had a balcony overlooking the lake and the breakfast room also has a great view. The free WiFi is on the main floor (not in the rooms).
One thing we didn't know from Rick's book is that you get the Salzkammergut Adventure Card free with a 3-night stay anywhere in Hallstatt. It gives discounts on many sites (including the Salt Mine Tour and the Giant Ice Caves) up to 30%.
