katherina and her roommate were very good host's. they provided everything you require for your stay at their place. their place is very close to the metro which connects you to everywhere in Vienna. There are also shops and restaurants in their neighbourhood so you have everything available. On a side note Katherina was very responsive to our questions when we were booking which came as a big relief becuase we tried 5 different places and only Katherina responded quickly with other hosts taking forever to respond or not at all. she saved us from the street so I highly recommend.
