Chris and Renata are wonderful hosts, and their apartment was much better than we have expected: immaculate, well-equipped, homey, and exceptionally comfortable. You will find everything you need.
Belsize Park is a tranquil neighbourhood, and you can find a supermarket and the tube station within 5 minutes walking from their place, as you can also explore the beauty of northern London and its vast space of greenery. A truly great British experience, would love to visit again.
