+ it was really close to the city center and palace belvedere
+ their communication was really smooth
+ really clean appartment
- we went to Vienna during a cold period and the appartment wasn't that warm and cosy as expected. I believe it can be a really nice stay in spring & summer
- The bathroom is very modern but the shower was not as great as it seemed (due to the fact that if you set the water power to hard, the water couldn't flow away).
Overall I would recommend this stay (except in winter).
