The pictures don't do this house justice - it's a beautiful, really high end home. The kitchen/living area is gorgeous with floor to ceiling windows that have a view of trees, with a lovely skyline view above from the upper floors. The private garden is lovely and there's really nice usable outdoor living space as well. We came with 3 kids ages 4, 7, and 7 and they were able to entertain themselves for ages on the playground!
Plus you're a quick walk from everything Hampstead has to offer - we would definitely book this place again.
