We had a lovely ten day stay in Laura's flat. Everything was perfect, including the West End location. Though the flat is on a very busy street, we did not hear street noise, and the location made us feel like we were living in London, not just visiting. A bus stop for bus 24 is just half a block away and the walk to Pimlico underground station is less than half a mile. We took public transit almost everywhere.
The flat has been redone too look like a classic London home and is beautiful, yet modern. We used the kitchen extensively and the washing machine as well (there is no dryer). The bathroom is workable, although with no shower curtain, the water does get on the floor, which is tile so not too much of a problem. The bed was comfortable, and the bedroom has a wall of built-in closets, so plenty of space. The TV and internet worked well.
Laura and Tom were excellent hosts, and though we did not need much as the flat was well prepared, they were there when we did. They let us check-in early and stay late, so were extremely accommodating.
I give their Airbnb the highest rating and would certainly stay there the next time we go to London.
