Dawn was very obliging. We didn't have any problems but, if we had had, I'm sure she would have sorted them out very efficiently. The flat is in an old building, but has been comprehensively and tastefully refitted. It wasn't quite as central as we'd expected (edge of Zone 2 rather than Zone 1 in London terms), but that's our fault for not studying the map more carefully, and it wasn't a long walk to the heart of the city.
