Hannes was a friendly and informative host for our short stay in Vienna! When we arrived he gave us plenty of local recommendations as well as a great tip to walk to Ruprechtskirche (the oldest church in Vienna) for a local Christmas midnight mass.
His place is cozy and colorful and we loved the loft bed. It is sturdy and comfortable unlike how some lofts can be. The kitchen was well equipped. There seemed to be a leak in the bathroom somewhere but it wasn't serious.
The location was quiet and central - we could easily walk to or take a short train to destinations. We didn't get to check out the 2nd district much as it was around the holidays and many local shops were closed.
We think it's a great deal for a couple who want to explore historic Vienna on foot.
