Found this place accidentally on a stop-over rest between Vienna & Munich.
Rooms were at a very reasonable price as compared to other guesthouses/hotels in Seewalchen. There were some outdoor insects as there are many flowers and it's close by to the lake, but we found none in our room.
Short walk to the beautiful crystal clear Atersee lake for swimming, ferry ride, water slide and activities in the area. This place has a great, reasonablely priced indoor/outdoor restaurant. Seems many locals eat there. Breakfast & Free parking included. It's a family run B&B -Tony, a charming young bachelor who manages the place, is fluent in german & english and very helpful with local information.
