If you want a hotel near to the museums (Natural History, Science, V&A) then this is ideal. You are in easy walking distance of all of these and Hyde Park, the Albert Hall, the Albert Memorial and many other places of interest and just a little bit further.
The room was very comfortable with a huge bed, a good bathroom with both bath and shower (and lots of nice bathing materials) and all the usual things. Free wifi was very useful but it seemed a bit slow.
We had a "club" room which gave us access to the club lounge. This is really worth paying the extra for. In the lounge you can have breakfast in peace, sit quietly during the day and meet for free drinks and appetisers in the evening. All very civilised!
The food was very good too. The breakfasts were great and really set you up for the day. The "fusion" style restaurant was also good as was the room service.
Staff were friendly and efficient, really very good.
This isn't cheap but in it's price range strongly recommended.
