 WiFi issues I have 2 devices which normally connect to Wifi and work well They didn t work in my room and variably in reception Either my devices aren t up to it or the hotel s WiFi facility isn t Both devices connected up drama free subsequently to Vienna airport which answered my question for me Restaurant attached to the hotel works well but probably need to book on arrival Saturday night told well it s Vienna and it s a Saturday night when no room Fair enough but I felt less esteemed by the tenor of the delivery of this message Lounge area of the hotel limited and the bar area is in the restaurant which is busy as a restaurant 
 My second visit the first as a couple with lady companion this time solo The location of the Erzherhog Rainer is spot on being a short walk from Karlsplatz U Bahn which is a hub connecting to a very efficient Metro system Stefansdom and the Museum Quarter are 15 20 minutes walk away In the opposite direction the Belvedere Palace is a short walk away The hotel itself has efficient and attentive staff My bedroom was functional and comfortable Breakfast is excellent served between 0630 and 1030 The first day I arrived for breakfast solo at 0900 to find there was no room bar an uncomfortable looking high table which a member of bar staff tried to fob me off with Issue resolved by arriving for breakfast at 0930 the remaining days and 0700 on my final day There are some very good eateries within walking distance of the hotel if the hotel s restaurant is busy
