I stayed here alone for 3 nights in June 2018, just visiting friends.
Key features/highlights - a truly awesome location with all kinds of shops, food, and transport options around, and Hyde Park and a gym nearby. A plush-styled older studio. I found the bed comfortable. An interesting way to open the front door using bluetooth on your phone is pretty cool. A responsive host (although I didn't meet her).
Things to note - shower pressure low but still passable, no fridge, two flights of stairs up (no elevator), no way to open door without your phone (so, if going jogging, must take phone), no drawers to put clothes but there are some hangers.
Summary - worth it for the good location and decent price.
