For our last day in London, we wanted to visit the Natural History Museum and stroll around the South Kensington area. To avoid dragging our four suitcases, I discovered the solution offered by Stasher: to drop off our luggage at Renzaki, a merchant (laundry) located just steps from the S. Kensington tube station. The registration, booking, and payment were done online the day before. Friendly welcome and after verifying my identity and the transaction number, seals were placed on the suitcases and the corresponding coupons were handed to us. For a deposit from 9:00 AM to 4:00 PM, it cost £24. A perfectly reasonable price for a perfect service.
