We've just come back from a great stay at Martin's place in Vienna. Communication with Martin was really good.
The apartment itself is very clean, the decor is lovely and the apartment is actually bigger than it seems on the photos. It is also really well equipped; my husband particularly appreciated the coffee maker, and the guide books and Vienna leaflets were really helpful.
The apartment is also in a really good location, there is a SPA shop next door to get provisions, there are plenty of restaurants and bars near by and it is just a 5 minute walk from Margareten- gurtel U- bahn (subway) station, meaning that it was really easy to get around.
