I have heard only great things about Grosvenor House, though I have never stayed there.
Regarding Amsterdam, I have a personal preference for the Renaissance there, it certainly has more charm, and architectural interest, after all, the Marriott there is just a giant concrete block, and the lobby is almost claustrophobic, but the hotel is not bad, it is a good hotel, just that the Ren is better, IMHO.
I've never been to Austria, so other people will have to agree or disagree with Sharon on Vienna.
I don't want to sidetrack this too much because he's asking for input & can do searches on both London & AMS & make his own decision on the properties should he stay in either city. I prefer the Marriott; you the Ren. To each their own. But did want to clarify something. The AMS Marriott is undergoing a major renovation on the ground floor that should be finishing up about now. The entire layout will be very different & open than last time you were there. I met w/ the GM when I was there last September & got the details; sounds pretty nice & I'm looking forward to seeing it when I'm there later this year (the rooms were renovated about a year ago), and when I'm back I'll update the hotel photos I keep on my website.
And really when it comes to both London/AMS, we all have our favorites. It's not like the OP will go wrong whichever property he chooses, assuming he picks a European city vs domestic or Asia. He's got a lot of good options from what people have posted so far!
Cheers.
