I stayed here for a few days, would generally recommend if you are looking for somewhere to rest your head and not spend much time in the unit.
Pros:
Convenient location as it is quite close to Piccadilly station and Kensington Park, good value, strong wifi, quick communication with host, relatively clean, has all the basics needed for your stay!
Cons:
Very small (especially the bathroom), noisier unit, missing key items many AirBnBs have (paper towel, shampoos, sugar for tea/coffee, etc), most of the TV channels didn’t work, older/less clean building.
Another few things to note. I came for work and planned to use the table seen as a desk, but it was too high for the chair, seems more like a standing counter. And the stairwells are small and have many doors between floors, so if you are bringing a full sized luggage, be prepared for a harder climb to the unit, which I believe is more than 4 flights of stairs.
