We really enjoyed the apartment. Location is perfect - very lively neighbourhood, full of students, with a lot of coffee places, restaurants and stores. Doesn't feel touristy as the San-Stephan area. Feels very safe even at midnight. Apartment is well lighted and very clean, and is perfect is size for 2 people. There are over 100 stairs, but after all the apple strudles we head - was a decent workout :) There is a Billa supermarket few meters away, and Spar in the next street.
I really recommend this place, and would love to come back. Self-serve check in was very easy.
