I'm planning to spend several days in Vienna sometime in the spring of 2013 (possibly April or May).
I'm looking for an affordable, single-person accomodation (preferably single room with bathroom) within the walking distance of the Maria-Theresien Platz -- I'm planning on visiting the Natural History Museum and some other museums which are all clustered in that part of the city.
It would be great if someone could personally recommend a hotel, pansion, or some other accomodation in that area. I would be eating out, so bed & breakfast would be quite enough. Anything up to 40 Euro per night would be great.
