Great flat! Very clean and 3 min walk to underground station, Alser strabbe. We walked to the Rathaus in 30 mins for the main Xmas markets and managed to find our way around quite easily. Also a 3 min walk away is a huge spar supermarket - so if you forget anything, no worries! Everything you can think of is there :) Nenad has lots of useful maps etc. in the flat. Everything you need is there! We did not meet Nenad but he left the key for us and communicated quickly between us landing in Vienna and getting checked in. WiFi is quick. Really good value for money! :)
