Seriously, if this place is available, just book it. Spotless, amazing location, great price and lovely host. What else do you want?! In London, places like this are like unicorns. Oh! And fluffy, expensive towels! And a fabulous shower! And a decent bed! And a proper kitchen! And a washer/dryer! All the important stuff if you are a seasoned traveler.
The place is literally round the corner from Borough markets, which is the best place for breakfast ever, and you are a block away from London bridge tube station, which services jubilee and northern lines. You couldn't be in a better London location. We are serial London visitors and we will definitely try to book David's place. Thanks David!
