First of all, this is a hotel with a confusing name. We booked the room of Hotel Lenas which is located at this address and that made me and my friend spent about 1.5 hour walking around the streets to find this out. None of any people there could help cause according to those people we asked for help, they are not locals. Finally, we manage to connect to internet using free WiFi at a nearby restaurant and we found the exact location of this hotel.
Actually this hotel is quite near to Metro station, Gumpendorfer Strabe, about 5 minutes walk. Room was quite spacious.
