We had a few weeks staying in Louise's place. The place is super clean! Louise provided us lots of amenities as you can have coffee, do the laundry, iron, Netflix and so on. He gave a welcome drink and snacks when arrived. If you need help, text to Louise and he will reply you in the blink of an eye!
You can get to the Kensal green station around 8 min by feet and spend another 30 min on the Bakerloo line to get to the central.
Only one drawback is the bit small room. As we are two people staying there, my girlfriend feels like we have small space and not enough to share.
Btw, I would recommend you staying here and I definitely go back.
