Best choice ever! Amazing room and quite central London.
I stayed at Katherine's for 2 weeks and I will certainly stay again. She was very kind and generous to me and always made sure I had everything I need. The place is within walking distance to the several bus stops and Tube and just 3 Miles walk to Notting Hill. It's also just a 5 minute walk to Kensal Rise where there are plenty of Bars, Restaurants, Supermarkets, Launderette, Florist, Park, so basically everything you need. I loved that I had the shower almost to by myself and was just opposite my room and as well another Toilet next to it, which were never occupied.
I also had the comfort of having my own little Kitchen in my room with Coffee pot, Toaster, Fridge, Microwave, coffee, tea, plates, so basically you don't even need to go to the main kitchen.
A perfect place to stay at comfort!
