We were a couple, a toddler and a grandfather visiting together. We foudn it to be a charming apartment, furnished and decorated with taste located on a quiet street from which we enjoyed strolls through lovely small lanes from Knightsbridge to South Kensington. The pullout couch was more comfortable than expected and there was more room inside the apartment than the pictures show. As indicated in the description, the entrance is at the bottom of a steep staircase, so you need to be nimble, but we found it added to the charm. And during the workday you can hear the steps and chairs of the office above. The lovely welcome and charming thoughtfulness of Bob was unsurpassed. Although we didn't need anything, I was confident that Bob would take care of anything without delay. He even offered to walk us around the area. Easy tube access and if you're walkers, the walk to the National Gallery was great. Great early dinner at the nearby Hawksmoor from the express fixed menu. We look forward to returning.
