We enjoyed our time at Karen's and Chris' place very much. They are great hosts that have travelled a lot themselves - that you can recognise in a lot of details when you stay at their place.
The guests actually have an appartment for their own in the basement of the house, even with a garden! Everything was very clean and spacious and the little things Karen and Chris organize for their guests - such as milk in the fridge, tea bags and some bread on the table - make you feel very welcome in their home. They have also prepared a little book for their guests, that answers all questions, and for everything else you can ask them.
The place is about a 10min walk to the train station Palmer's Green and 20min to the Underground Southgate or Arnos Grove, so public transport is not next door. But it's situated in a wonderful neighbourhood and we enjoyed the calmness and peace after coming back from a busy day.
