Great location for "off the beaten path" London. It was a quiet, residential, and clean stay. Perfect for two people who didn't spend a lot of time in the room.
Having staff nearby at the front desk was helpful -- they stored our luggage and ordered us a cab. There were little "extras" around the building if we needed more tea, soap, or toilet paper.
However, the room isn't cleaned daily and there is an extra fee for late check-out.
Would definitely stay again!
