The Thistle Hotels are a UK national chain - mainly 4/5 star hotels. The Thistle Victoria is actually part of Victoria station - location is great for access to LGW (train) and west to LHR and central for the West End/ Buck House etc.

I am pretty sure the place has been refurbished, and am confident to a high quality - and and will have all the restaurants and cafes you need. It is also a historic building/piece of architecture in its own right and certainly better looking from the outside than most of the large hotels in central London....

Not sure that it is up in the luxury bracket - but I think 4 star at least - all of which makes me wonder what your price range is or maybe wonder whether you have a good deal worked out?!
