We loved Bernhard's apartment in Vienna! He is located less than a mile from a u-Hahn stop and a trolley drops off right in front of his building.
We never had the pleasure of meeting Bernhard, but his instructions for access to the key and entering the apartment were very easy.
The apartment is beautiful. It's modern with plenty of storage space to unpack your suitcase. We found the bed to comfortable and enjoyed the light that streamed in through the windows in the morning.
This was the only apartment on our European vacation that didn't require multiple flights of stairs and for that we were thankful.
This was our first time to Vienna and we loved every minute. If we ever return we will absolutely stay at Bernhard's apartment again.
