Our week in London was made so much easier by the location of this flat in Fitzrovia. To Americans, the neighborhood will be reminiscent of Greenwich Village in NY: lots of shops, restaurants, fast foods, and, generally, a lot of life. The location is central to just about everything, easy walking distance to Leicester, Trafalgar and Piccadilly, plus convenient to several Underground lines. And the Underground is a miracle of efficiency.
The flat had everything we needed and was perfectly lovely. However...
The ad for this flat is misleading. Simply saying "Not Handicapped Accessible" or "No Lift" does not convey the fact that you will have to haul your suitcase up three steep flights of stairs (because the ground floor is Floor Zero, so the third floor is the fourth floor). This will be extremely challenging for older travelers. We found that, once we reached the room at the end of the day, we weren't wild about going out because we knew we'd have to trudge up 3 flights of stairs--again.
