I stayed at N11 last week end with my family and some relatives and we all enjoyed it very much. Chelsea is my preferred neighbourhood in London anyway, but this hotel is special since you feel like staying in a real English home. I like the building, the decoration, the linen, their breakfasts in classical English china, and the service. For sure I will go back.

Eleven Cadogan Gardens is like visiting your old rich aunt who leaves in 19th century splendor. The hotel was, in by-gone days, a stately mansion in the middle of the city. Now it houses one of the most sublime experiences to be had in London.
Now, don't expect "corporate hotel" glitz. There is no glitz. Just warm, understated, highly personalized service and comfort.
The staff is invisible - until you need them. They appear with the press of a button. The walls are wood paneling, aged and beautiful. There are old paintings everywhere. The furniture is down-filled and covered in silk damask. But the attention and service are on a par with the finest hotels anywhere.
This is definitely a place I'll return to.

We've stayed at 11 Cadogan Gardens every time we visit London, but I was never a member of Trip Advisor before, so this is my first "review". There is no hotel like this one. As others have said in their posts, it is more like coming home to your own palatial London address than staying in a commercial establishment. And for those few who were offended by the "stains" on the rugs and the age of the furnishings--we love the age and beauty of this place. If the carpeting isn't brand new and spanking clean, it's only because so many feet have danced with joy over these floors before ! If you want to experience London as a true Englishman (albeit a wealthy one) rather than a tourist, this is the place.
