As a mature couple in their 60's we did not find this flat as comfortable as others have noted. Shortfalls for us were lack of storage space for clothing, bed pushed against wall meant a climb over situation, the hand held shower in tub was a real nuisance, one needed to be quite fit to bathe! finding the key at a local grocery was more difficult than expected because it wasn't sign posted. It was unusually hot for London during our stay we were grateful for the small fan provided. Location was good. Katherine did come by to show us a few things which was helpful but my understanding was that its usually "turn key".
