I stayed at Kofi's house for 2 and a half weeks - it is a family house so you share bathroom & kitchen with the family; the bedroom is nice with lots of storage which was handy as I had 2 suitcases with me!
Kofi and his family are kind - I didn't see them much as I was at work most of the time but they were helpful when I needed as well as flexible. I was able to use the washing machine and change my bed sheets in the middle of my stay.
I mainly used the kitchen for the microwave & kettle and was able to store a few items in the fridge.
The house is well situated, not far from Kilburn Park station.
Overall nice and affordable accommodation!
