I'm pretty sure I have looked at every single airbnb in London over the last 3 days!!! We are doing a long layover after our Croatia trip in June. We also ended up in an apartment on Baker street in the Marylebonne area, could it possibly be the same as Eva's??

My friends in London also suggested Kensington, Knightsbridge and Marble Arch areas. We have booked Airbnb for our stays in Split and Dubrovnik as well. So far good luck with all of them!
