 Our room was too hot the air con didn t seem to work so we informed a member of staff The first member of staff advised us to open a window obviously we d already done that but this really didn t make a difference as it was warm outside and the window barely opened as it was Eventually we complained again and were moved rooms but I m not sure that the air con really worked in there as well Second member of staff was really great and overall our experience was very good but can t imagine what it would have been like in the middle of summer as it was only between 20 and 25 degrees when we were there and I m usually always freezing 
 Good location by the train station tram and U Bahn Really modern and well designed hotel Friendly staff members bar seems to be open 24 7 Easily located big sign on the side of the hotel Internet TV and the map on the wall of Vienna were really helpful Would recommend
