Great facilities, great location and perfect for anyone going to the UN offices in Vienna. The view over Donau Park and Vienna is spectacular both during the day and at night. Access is easy from Kaisermühlen - VIC station on U1 metro. Access from the Airport via the S-Bhan (Service S7) and Metro U-Bhan Line 1 is straight forward.
Sladan is an excellent host and I have no hesitation recommending Sladan's place to anyone visiting Vienna.
