Stayed here in one of the one bedroom suites looking out towards the Houses of Parliament. Fantastic views, great quality feel. Overall the location is not as central as you might think and the drawback the weekend we stayed was that the Victoria line was closed for maintenance, which meant we had a brisk walk up to Westminster each time we went out. When the Victoria line is working Vauxhall is the nearest tube about 5-10 minutes walk away. Caught a taxi one evening from Waterloo which was only £6 so you have that option. Valet parking for your car works well at a price £26 per day, which for London is probably reasonable. You do get charged extra for the third person on a sofabed in the suites, even though we had made it clear there would be 3 people when booking.
Kitchen diner in the suite works well and allows you to take your own breakfast ingredients. Only thing that was wrong was that we reported the toaster as faulty and a member of staff removed it. Only thing was it wasn't replaced while we were there.
I would stay there again as the room quality was so much better than many places in London and the staff were excellent. Just need to be aware you are not in the main tourist area, but that in reality is not a bad thing!More
