Gerd was a most accomodating host, providing clear directions leading up to our stay which made our arrival prompt and hassle free.
The place is spacious and well kept and Gerd provided all necessary accompaniments to make our stay as comfortable as possible.
The apartment is close to public transport and the city centre was a short tram ride or, alternatively, a pleasant walk.
Overall, it was an awesome stay at a reasonable price. I would highly recommend Gerd's place to other would be visitors to beautiful Vienna.
