Booked a midsize to drive to London and help a friend move out of their rental house. The reservation was made the night before, and the car was ready when I arrived. They gave me an SUV, a 2014 dodge journey to be exact, which is bigger than a midsize. I didn't mind though considering what I needed it for.
The cars are located in the parking garage below the soho metropolitan hotel. The garage is accessible 24/7 and there's late night dropbox for any after hour returns.
