Orkun is a kind, nice and helpful guy. At check in moment, my phone turned off and I couldn't contact him, so he waited for us near home. The apartment was really clean, warm and neat, with all the necessary for a comfortable stay in Vienna. We were four guys, and maybe the davenport is a bit little for two adults. Beds were comfortable, the toilet was well sized, as the bath. The Kitchen is equipped with all the domestic appliances (oven, microwave oven and induction cookers). We had just one trouble: because of the snow, the Wi-Fi has stopped working, but Orkun was always there for us, and he tried to solve the problem. Unfortunately he didn't, so he made us a little present as an excuse for the inconvenience. Geographically, the apartment is in a very pretty neighborhood, near a supermarket and the bus/underground station... Moreover, it's a twenty minute walk to the city center.
I give the maximum score to this experience because it's been really positive!
