The flat is perfectly located. Only a 5-7 min walk from the begining of the city center, public transport in front of the door step if you don't want to walk. It's quiete and peaceful, but still, there are a lot of shops, bar, coffee places, stuff like Naschmarkt, wonderfull places like Ressel Park and the Technische Universität around the flat too, so you don't have to travel so far to check the beauty of Wien as it is.
Sanda was friendly and really cool as we came by the bus from Praha which was a bit late, on a sunday.
Thank you Sanda.
