We recently stayed for 2 nights at Amanda's place and I can thoroughly recommend it. I stayed over with three of my colleagues and the place gave us sufficient space to do our strategy meetings and feel as though we had the benefit of a retreat. Nearby Queens Park is great for an early morning run and the shops and delis around Kensal Rise station are great; please do check out the Caribbean restaurant island on the rise next to the station, the 2 lunches for £10 is excellent value and quality.
The second night we hosted a barbecue for our team and the garden was ideal : the space in the house certainly came in handy when we had a few extra guests for breakfast. This is a lovely house in a great area, it's very clean but you don't need to worry about taking your shoes of when you go in, perfect for entertaining.
