This house is on the second floor (where you see the stairways is leading to the loft or attic rooms) and the rest is as described by the host and all is good for travelers who are not physically challenged to climb steep stairs.
It is a designer house with chic-finishing and greatly suited for adults, not for young children. The location is central for tourists within half hour walking distance to Hyde Park, Buckingham Palace and all sightseeing attractions near Big Ben.
