We had such a fantastic stay at Salim's apartment. The tube stop was on the Piccadilly Line, which was super central to everything we wanted to see, we were walking distance from the British Museum, and it was awesome coming back to an apartment instead of a hotel room each night. Salim was fantastic at communicating with us as well!
I will note though that this apartment is probably near a hub for emergency vehicles as we seemed to hear a lot of them at night, but no more than we would have at home.
