Small but nice apartment, it has everything you need. Building is a little bit rusty, but place is really nice. Best part is apartmant is at really great location. Close to Mariahilfer strasse (main shopping street), close to subway, 20 minutes walk to center of Vienna. A lot of bars&restaurants in the area, as well as nice parks.
Chris&Tina are nice hosts, flexible and easy to deal with. I would definitely stay again here.
