The Zetter Townhouse Marylebone opened its doors in 2015. The second addition to the independently owned Zetter Group’s ‘Townhouse’ boutique hotel family, the 24-bedroom Georgian townhouse and cocktail lounge enjoys an enviable location on Seymour Street in London’s fashionable Marylebone. Feeling more like the private home of an eccentric relative than a conventional hotel & bar, the property features 24 bedrooms and an award-winning cocktail lounge, Seymour’s Parlour. While The Zetter Townhouse Clerkenwell is known to some as the home of The Zetter’s Great Aunt Wilhelmina, the Marylebone property is the next in the family and is that of Wicked Uncle Seymour.
