Luxury hotels in Vienna – any recommendations?

We recently stayed at the Sans Souci Vienna. It's big, but it has every luxury you need and the service was excellent. Breakfasts were the best we've had in Europe and the restaurant was very good in the evening. It's on a busyish corner, opposite a metro station and it was easy to get around on foot. We were there in cold December so I've no idea what it would be like in Springtime.

@MartavTaurus Thank you, that's very helpful! I've just had a look at the Sans Souci website and it really does look lovely. The rooms seem beautifully decorated, and the spa particularly caught my attention. I noticed they have quite an impressive indoor pool too. Did you have a chance to try the spa or swimming pool during your stay? I think that might be something our friends would particularly enjoy. And it's good to hear that the breakfast and restaurant lived up to expectations!

My daughter in law once stayed here - Hotel Sacher (!!!)

Conde Nasty!!
😂

Sacher Hotel is the traditional style equivalent to London's Savoy or Claridge's. Mind you, it's many years since I stayed there!

Be careful, We got bitten to death by bedbugs in a high end hotel in Vienna. After complaining afterwards and sending photos of our countless bites we were offered a free night as compensation. As if!
