Perfect experience in London.

The communication with Lauren was very good (thanks to her). The apartment is as promised, and easily accommodated the 5 of us (3 kids and two adults) in bedrooms (one another couple could have slept in the living-room). The apartment was clean on arrival, it is fully furnished and we were very happy to enjoy the small yet numerous attention provided by our host, such as the clean towels provided by our host.
We have selected this place because it is close to to Liverpool station (direct train to Southend airport). The location is good for sightseeing in London: it is close to numerous transportation facilities (buses 21 and 141 about 100h meters from the flat, subway in Old street allowed us to move to most popular places in London in typically 30 minutes, at most 40 minutes for the farthest ones).
Bottom-line: not ultra luxury, but quite a good place (and price) for sight-seeing in London when you have many kids.
