The guesthouse is in Alpendorf (essentially a skiing village, although we stayed in summer), a short drive from St Johann. There are a number of other hotels in the resort - mostly 4-star - which provide somewhere to eat out / have a drink in the evening. There is just one small shop in Alpendorf, which is only open for a few hours a day.
We enjoyed our stay at the Pension Forsthof, and used it as a base to visit many beautiful places - Austria, and this part in particular is glorious in the summer.
We had a pleasant, good-sized room with a balcony. Although we prefer baths to showers, the shower was of a very good standard. The staff were friendly, without being intrusive, and we enjoyed the informal "feel" of this guesthouse.
