Daniella’s mum welcome us and was really lovely and give us lots of tips.The area is really quiet, 10 min walk to Rennweg (metro and train station) and tram 71 is really confortable to be at the city center in 10 min.
The airport is 20 min by train(S7) and if you have the 24/48/72 hours ticket for the all public transport(high recomended), the ticket for the airport train will cost only 1,80€!!!
The main train station HLB is 20min walking from the apartament(we arrived by train and did it, and we have no problems, and the street were quiet)
The supermarket HOFER(cheaper than Billa) is 5-6 min walk and pizza is good in ristorante ROMA (fassangasse st. near Hofer)
Maybe when it is sunny the apartament is as lighten as in pictures, when we stayed found it dark, and the building older than expected has a improvement in progress and it makes noise, anyway they are almost finishing so maybe is now better!
