It was really nice to stay at Andrej's place. Staying there for 2 months made me feel like living in my own home. Everything in his apartment is perfect. Also, Andrej is more than just a host! He treated me like a friend, he invited me for ice skating (which was my first time and really fun :D).
I really recommend to stay in his apartment while you are staying in Vienna for a short or long time. You will have a great experience!
