I will be traveling to Munich, Salzburg and Vienna in March with two other people. I am considering staying at the following hotels and wondered if anyone had any previous experience staying at these locations. Munich: Hotel Blauer Bock, Salzburg: Hotel Trumer Stube, Vienna: Hotel Pertschy or Pension Aviano.
I stayed at Hotel Blauer Bock in June. Centrally located, clean room and update bathroom, good breakfast. The staff was friendly and helpful. I higly recommend the hotel.
We are traveling to Munich in March also and booked an apartment http://www.zimmer-guenstig.de/en/zg0001.html
They have been very quick with reponse for us, and convienient locations. Maybe this is something that would work for you also? Hope it helps
