Beautiful, clean classic Austrian hotel, Excellent & very helpful Concierge, very nice rooms. Only problem is was the Air Conditioning, room hot temperature. 1st room, after 4 tries, they said A/C didnt work and could fix. So they moved us to a 2nd room. 2nd room was very nice, buttttt, similar room heat problem. Problem--- only 1 of 2 AC motors were working (hall AC fine, bedroom AC was broken & would take hours to fix). So at 11pm we changed to a 3rd room. Its AC worked fine.
Front receptionist team were nice people, but were limited as to what they could offer. No portable fans are available (would of been a solution) and staff explained the hotel was older, as is the AC system.
Again everything except the AC was excellent about the hotel, great location and wonderful Concierge.
