I had a great stay at Raul and Carol's place. The location can't be beat and I didn't find it too noisy at night at all. Checkin was very smooth, and Raul even provided a video to help with a sometimes tricky front door lock (I didn't have any issues).
The bed was extremely comfortable and the apartment is beyond spacious for London standards. I could see it being a great spot to stay with friends.
Highly recommend and would stay again!
