 for a 4 stars hotel there should be a porter service Internet service wi fi was very difficult to sign in and to access except only 1 front desk clerk Lopez knew how to help us access the wi fi it was user unfriendly Also the one 1 nite guaranty leave us in limbo for refund when we paid cash for our entire stay How long will it take for refund to my credit card 
 all ok croissant not over flaky Bed ok it was all acceptable More towels would be better also a recommendation a small shelve in the shower and a hand grip bar Hooks to hang our bath towel etc Helene Wiederkehr our stay was 21 25August VIENNA
