Adrian and Stephanie were lovely hosts, and the whole flat is extremely clean! Having breakfast included was awesome, and although it is not right downtown, I think it only took us 25 minutes to walk to Big Ben area, and it's decently close to the Tube at Pimlico.
When our pulling adapter wasn't working, Stephanie graciously allowed us to use her plug to charge our phones overnight.
Overall a very lovely flat, with great hosts. Would definitely recommend.
