Nikola's apartment is very well designed, modern and wonderfully equipped. When we walked in it was exactly as displayed in the photos, with everything spotless, and in place as if it was for a photo shoot. It is a great base for exploring Vienna - we walked everywhere within twenty minutes but could also use the metro, with the stop just at the top of the road a few minutes away. We did not get to meet Nikola personally but he left us with extremely clear and helpful information about everything in the apartment, and in Vienna. He also gave us great advice by email about what to book in advance, left us a welcoming beer in the fridge, and responded within minutes by email to our one question when we could not work out how to use the cooker. He very helpfully arranged to return a couple of small items of clothing we forgot when we left. So though we did not meet, he was a most welcoming host.
