 Absolutely nothing you were all wonderful 
 Everything about this exquisite hotel was fantastic From the welcoming staff to the comfy bed gorgeous room which was cool cool cool to return to after a hot days sightseeing in Vienna The food in both restaurants was faultless The staff were more than helpful kind and generous with their time answering questions and guiding us through the maze of activities we could do during our stay We highly recommend a stay at this unique and beautiful gem in the heart of Vienna Cant wait to return and thank you all for a truly special and memorable visit
