The host being away on business, we were greeted by the host's housemate, who was friendly and helpful, giving us keys and info about local transport, etc. The housemate was hospitable in letting us share the kitchen/dining/sitting area, which is on the flat's first level. The kitchen is exceptionally well-equipped. A cupboard and a fridge shelf were reserved for our food and drinks. On the flat's second level (15 steps; good handrail) are two bedrooms, each with its own bathroom. One was occupied by us, the other by the housemate. The guest bedroom has an excellent cupboard that accommodated three suitcases worth of our stuff with room to spare. The bed was firm and comfy. There was adequate space on either side of the bed. The radiator worked well. The bathroom -- not literally attached to the bedroom, but just next door -- has a skylight and modern fixtures. We found the flat's location convenient. A seven minute walk (at our slow pace) took us to a bus stop. A seven minute walk in the opposite direction took us to a different stop. Thus, six or seven bus lines are nearby, each running to places we wanted to go, like the National Gallery, Hyde Park, and the theatre district. (A bus whisked us home at 11 pm after a show.) A tube station is a 15 minute slow walk away.
