Very grand hotel perceived when you first arrive, the reception/lobby area is magnificent as are the stair and hallways. This illusion is swiftly over when you get to your room. I have never been in a room so small! Avoid the single rooms at all cost. Perhaps I was unlucky and received a particularly small room but for the price I paid I expect far more. I could quite literally touch the width of the room with arm and leg without going horizontal - I tried. So say 5' wide.
Later on in my stay I changed my booking and was 'upgraded' to a twin room which was far more comfortable.
No minibar in either room.
Excellent gym and I spent a considerable time there as I didn't have much else to do.
At breakfast the restaurant was usually quite busy but worth going as the full English was excellent and the staff was mostly friendly.
I wasn't overly impressed with the restaurants at evening time but I wouldn't say exceptionally poor.
For roughly the same cost I stayed at the Double Tree Hilton during the same month however I would certainly prefer the Grosvener.
Free Wifi is a plus and the speed was good.
Business center - appalling. A hotel as large as that with only one computer and no scanner (there was one there but not hooked up) is poor.
I expect more for the price but perhaps I am deluded in thinking this is the case in London-Victoria.
Oh and I'm still waiting for a copy of my invoices - it has been two weeks now since my stay and several emails have been sent requesting the scans. Should I send some more reminders?

first the good, fantastic location, part of victoria station, but no noise, impressive hotel, great bedrooms, great reception and concierge staff, nothing to fault all up to standard of a hotel of this grade,

the not so good, the bar staff, awfull, waited and waited, and ignored, at the bar to be served, offered to pay for drinks was told do it later, offered to charge it to room was told no problem do it later, when i had to leave to go to room to get something, was stopped , ''you must pay'', i was told, ''but ill be back'', no you pay now, ''heres my room card charge it,'' no you pay now, i was made to feel like a criminal , awfull customer service, rude and quite agressive, then the breakfast, get there early , if not be prepared to queue in the corridor, once seated i was told the staff will serve tea coffee and toast, hmmmm only if you ask 3 different members of staff , six times and sit and wait and wait and wait, to be fair though i think they were understaffed in this area, and the staff that were working very hard hard were overwhelmed,

overall a great hotel , cant fault it, but please sort the bar staff, rudeness and ignorance are not a good reflection on a good hotel ,

Our recently refurbished room was large, quiet and comfortable with all the amenities expected of a 4 star. The Reception, Concierge, Cleaning and Lounge staff are all extremely pleasant and polite. The location is terrific, being adjacent to Victoria Railway Station - handy for the tube, mainline rail, Gatwick Express and Big Bus Tours. Short walk from Westminster, Buckingham Palace and Hyde Park. Afternoon tea in the lounge is a real treat, dainty sandwiches, fancies and scones with jam and cream. Highly Recommended.

We spent the weekend at the Grosvenor and I cannot commend the staff enough for making it very special for my Fiancee' and I. It was a special occasion as I proposed to my Fiancee' on that weekend. We were within an Executive room with access to the Executive Lounge and the experience will never be forgotten. On arrival we were met by the assistant manageress Ines Weifenbach who escorted us to the Executive reception area and gave us a fantastic welcome. On returning from proposing to my Fiancee', we were given our rooms earlier than expected. The room was first class, sheer luxury. The room was spacious, elegant and had all the facilities as described on the Grosvenor website. The Executive Lounge was brilliant. Breakfast till 11am, tea, coffee and snacks served during the day and alcoholic beverages in the evening. The staff were really nice and helpful, I cannot praise them enough for making our stay comfortable as well as memorable. Special thanks to Ines and her staff. Peter, Natasha and Sandra within the Lounge, you were all great, thank you.
