Amar is very friendly and helpful. He walked us to the train station on our first day and helped us figure out which underground card would be best for us. He gave us lots of pointers for our trip and was extremely friendly. His roommate was also very friendly. His home is just outside of the hectic center, allowing for a more peaceful night, but if you don't mind a short walk (which you'll be walking everywhere anyways in London), the train that takes you straight in the city is fairly close. I would definitely stay again, one of the best hosts I've had through AirBnB
