So named as its bedrooms and terrace are sky high, Treehouse offers panoramic views over the landmarks of London and one of the quirkiest, yet fanciest hotel stays around. It’s designed to engender the same kinds of cosy, adventurous feelings of childhood clubhouses that were built among the branches, with vintage furnishings and pops of colour. But it’s all very upmarket and bang on trend. The Nest is the big event here; a hip, bohemian day and night spot, offering sublime food, mixology, DJ beats, interior foliage trailing from the ceilings and 360-degree skyline views. There’s also a Mexican restaurant, a pizzeria and the Backyard cafe hangout.
