We stayed at the Hutton 4 nights on our visit to London.
Our room was pretty basic without any extra space, but I think this is fairly normal for London hotels. Our bed was comfortable, our room was quiet, and we slept well.
On the positive side, we found the location great.
Walking distance to the Victoria station, Pimlico station, and many attractions. The bus stop is right across the street. There are nice restaurants within a few blocks too.
We found the front desk people helpful, communicative, with good advice.
We would stay at the Hutton again.
