We had a good & comfortable stay at Mandy's. The place was very clean, the beds very comfortable, the kitchen quite well appointed, and Mandy answered our queries promptly.
It is awkward that the toilet and bath can only be reached by going through one of the bedrooms.
Also awkward for us was the fact that only one key was provided in spite of numerous requests for another one. Lockbox is fine if everyone is out at the same time, but if one guest wants to sleep and another to stay out late or leave early in the morning, it isn't really an option to be locked in/or be woken when the one who is out comes back.
Another consideration for summer stays is that the lovely upstairs living-dining-kitchen area heats up quickly and cools down slowly.
Overall, a nice place to stay in Shepherd's Bush!
