This Hammersmith studio was very clean and close to the tube. I appreciated the cleaning/towel refresh daily and the check-in and out process was very easy with a wonderful host at Aviva studios. The air conditioner worked fine (make sure to flip the switch). My only comment is that the photos did not match the actual studio and we were in one with a very slanted roof which resulted in many banged heads over the course of the 3 days. I would recommend!
