Really nice flat and extremely good communication with the host. Although we arrived on Easter Sunday (when everything is closed in Austria and people go away for the holidays) Ella organised everything perfectly. She even had booked us a breakfast table across the street while we were waiting for the check-in.
The location was superb for our needs - bus, tram and metro stops were all with less then 5min walking distance, grocery shop next door! and fantastic Italian place on the same street 2 min walking ;) (might of been names "I Caruso" or smth - just remember bring cash since only bank card accepted was the Austrian "Bankomat")
Although the flat is on the 3rd floor, it can be accessed with elevator (very handy when you have 4 suitcases).
I would recommend Ella as a host and her flat without a doubt!
