Katrina's place is wonderful.
The room is very large, and extremely well-appointed.
The location is exceptional; very close to the tube at Highgate, and a short walk to both Muswell Hill and Highgate, where there are plenty of excellent restaurants and cafes.
Katrina and Duncan made me feel very welcome from the moment I arrived, and were thoroughly attentive throughout my stay.
I would gladly stay here again anytime I'm in London.
