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?
