Nick himself wasn't there, but he arranged to have his roommate leave the key for me in the local food store. His roommate Moritz was very friendly and helped us to change the sheets and made sure we had everything we needed. The traffic from the street can be quite loud with the windows open, but I did not find it too big a distraction to be able to sleep. The apartment is big and has great high ceilings. The flat is located very close to the Praterstern Bahnhof which has connections on many different lines. It is also only a 15-20 minute walk into the Innenstadt.
