I'll be traveling to Heerbrugg on business regularly after this trip. Most colleagues stay in Dornbirn across the border, but they were all sold out. Found this place and was on the St. Gallan to Heerbrugg rail line so I gave it a try. Amazing. Better cost value than the Sheraton Four Points in Austria. True castle with all modern room amenities. Honor system for helping myself to a bier after desk closed. So unbelievably quiet inside during the night time. Fabulous restaurant. Beautiful grounds and walking distance through deep woods 5 min to Staadt Bahnhoff. The staff and the nearby people were tolerant of meine High School Deutsche Sprachen...and I was far more polite than most of the other Americans I encountered closer to Zurich. My only fear is giving it a 5 star rating means it'll become too popular and I won't be able to book for my upcoming trips :-) . If you want a hotel with a hot tub and 24 x 7 wait staff or front desk, then this is not your hotel. This is, in my opinion, an amazing place for recharging, locking yourself away to write proposals and tedious powerpoint decks or just reading and staying away from humanity for a few days.
