Mario's and Dagmar's apartement was as nice and stylish and located in very good area. Metro station was around the coner and to Main Train station was possible to reach within 10 minutes. Very good connection from and to the airport via Regionaljet train - quick (15 minutes) and cheap (4.10 eur). Only thing you must know that rooms windows are open onto the street and there are traffic all night long - so it is bit noisy. Otherwise everything was perfect. I definetely suggest this apartement for a short stay.
