We had a really positive experience of using Ruth's flat. We are a family with a young child and it perfectly met our needs.
All Ruth's communications in advance of arrival were timely and clear, she left us a little package of essential food items and the flat was clean, well equipped and v spacious.
I'd definitely use again and would recommend as a really good base for a stay in North London.
If you're in London with young children, this is a particularly good option.
