Stefan’s place is amazingly located close to the subway and the Vienna downtown circle. It is comfortable and very clean. We did have a couple of glitches along the way (for instance, the heat wasn’t working when we arrived), but Stefan promptly responded to us when we reached out to him and fixed any problems we had (and they were pretty minor glitches).
Very reasonable place for our group of four and I must say, one more time, that the location was fantastic!
I would definitely stay there again!
