This is a nice space with a roomy bedroom and lounge. Check on a map you wish to be on this side of town, although the underground network soon gets you around. There are some low beams in the apartment since it occupies part of the roof space. It was spotlessly clean and is bright and cheery. Do not count on there being any salt, pepper or sugar in the apartment since this seems to rely upon the previous guest.
Rudolf's communication was excellent, as were the instructions for finding it, although if arriving from town along Margareten the numbering is confusing, since at No. 75, the next number is 2, as you are on Margareten Platz for about 30-40 metres. Keep your eyes out for Cafe Cuadro and you will not go wrong.
This is a nice apartment, reasonably priced for Vienna.
