We only stayed one night but it was and awesome stay. The people from the time we pulled up until the time we got our car the next day could not have been better.
Our room was very nice but on the street side as they had renovations going on there where no river side rooms available. The renovations really did not effect our comfort outside of not having a great view of the river.
We did not eat at the Sacher but we did spend some time at the bar and had a few drinks and a cigar at the Bar. Alexander was great to talk to and is a very bright young guy with a good opinion on hotels and restaurants in Europe.
I loved this place, its on of the nicest places I have ever stayed. Its one of the few places I have been that really deserve the 5 star rating I give it. I feel "excellent" many times is over kill for many places I have stayed but "very good" just seems a bit short. I think in this rating system maybe an exceptional rating should be in order. The Sacher was everything I would expect from a world class luxury hotel and hope I make it back sometime soon.
