 I stayed at the first floor where some renovation works were going on Actually I was hoping to have a renovated room but when I compared with the pictures at booking com my room seemed to be old fashioned and not so fresh so be careful what type of room you book Water was coming out every time I had a shower I found wifi not to be stable enough many interruptions as working at nights Again another hotel with no ventilation at all at breakfast room so be prepared that your suit will smell the whole day bacon and eggs 
 This was the first time at Der Wilhelmshof I booked here because of the overall rating and the nice pictures at booking com and the proximity to public transportation Praterstern train metro bus and tram station is just 5 minutes walking time and the city center or the Vienna International Center is just a few metro stops away Also from Praterstern there is a direct train link to the airport in 20 25 minutes Staff very friendly and very nice breakfast I liked very much the bread variety
