B&B Vienna

Google: Hotel zur Wiener Staatsoper. Called a hotel but it has no restaurant - just serves breakfast - so I think that it is actually a B&B. Nice place in an excellent location.

Pension Nossek (Graben 17, 533 7041, www.pension-nossek.at, €110)

Jim, we've taken rooms several times at Pension Nossek; see above URL. It's very comfortable - and historic (Apparently, W.A.Mozart had an apartment somewhere in the building). Pension Nossek is located quite centrally on The Graben, No. 17. Gute Reise!... p.
