My GF and I had a great time as Bernhard's apartment. It was exactly like it is described and also as shown in the photos. It snowed in Vienna for the 3 days we were there and it made Bernhard's place magical.
We felt like we were staying in a room in a fancy resort.
Bernhard met us upon arrival and showed us everything we needed to know. He was a very nice nice and friendly guy.
The bed was comfortable and the place spacious. The apartment was fully fitted out for preparing meals if a guest wanted to. Though we chose to eat out :)
The apartment was easy to get to. Only 3 blocks from the metro station. It was also really well located. We walked from the apartment to the centre both days as the adjacent main street is a great shopping boulevard and leads directly to the main museums and centre of Vienna.
The only small negative we experienced was keeping the room warm with all that glass when it was -4 outside!!!
We would highly recommend Bernhard and his place.
