The Zetter Hotel, London
An alternative option for London is The Zetter in Clerkenwell, near the city. It has 59 boutique rooms, each individually designed with a vintage-modern style. There are also seven rooftop studios, each with its own private terrace with incredible panoramic views of London.
There are a number of eco-friendly practices including a borehole beneath the building that cools the fridges and bedrooms, environmentally sensitive building materials, chemical-free shower products, as well as an in-house green team. The onsite restaurant is also one of the founding members of the Sustainable Restaurant Association.
