An excellent trip to a wonderfull city, hosted in a very comfortable flat.
Markus and Lucie helped us very much at our arrival with usefull and interesting information, both concerning Vienna, the transport network and the appartement.
The only problem to solve is the young neighbour living downstairs playing drums in the evening (3 times during our visit of 6 nights, even though we talked to him). Lucie told us that she was going to meet her mother to talk about it.
The appartement is perfect both for cooking nice meals after a day out in a fully equiped kitchen and having a nice sleeping experience in king size beds. So comfortable that your don't want to leave them in the mornings and get out to start the visits ;)))
If you want to take baths, think to ask Lucie for the thing to cover the drain in the tub as it was missing on our stay.
