I just spent a night on a business trips in Brown's a hotel by the Rocco Forte Hotels.
This is a classic London Hotel in a great Mayfair location, so great for business and luxury shopping.
The rooms are huge and well equipped, although I would have liked a separate shower, and the lack of Wi-Fi connection is an issue at this price range in my opinion.
Staff are helpful and efficient.
The two small issues are: they have refurbished the hotel recently and I beleive the new furniture added does not match the period features of the hotel, it is neither modern and minimal nor classic- it is just not classy in my opinion. The another-the breakfast: I ordered an English breakfast and thankfully arrived fairly early, because it arrived 25 minutes after my order. I think that is unacceptable at a hotel this cathegory.
