Nikola was a great host. He communicated back immediately, with lots of good and useful info, and even with a Vienna guide. My flight was re-routed while in transit, so I ended up in Vienna unexpectedly early and Nikola responded very quickly while I was travelling and ensured I could get into the flat early, to get some sleep after a long flight from Australia.
The flat is just as it is pictured and set up to a really high standard - warm, clean, light, comfortable, good bed, well laid out, and with everything you want. It is really well located for both walking to the city centre and museums, and for public transport. A great place to stay and with a very helpful and thoughtful host.
