Appartment is easy to reach from city centre and with its historical vibe does contribute to experience of historical Vienna. We really enjoyed the fact of it having somewhat a personality instead of being a sterile, boring, no matter how modern hotel room. Having said that, I will also point out that it was clean and had everything we needed for our stay, and Daniel was welcoming, precise in his advice on how to get to the apartment as well as general tips regarding surviving in Vienna 101 before our trip, and helpful when one of us had forgotten how a door key should be used and needed an instruction on that. :)
Would recomend this apartment without any hesitation if anyone asked where to stay in Vienna.
