This apartment is incredible for any trip to London where you want to be in the center of it all but still feel like you're in a quaint neighborhood. Fitzrovia is like a cross between Chelsea and the West Village in New York City - cool galleries, interesting shops, amazing selection of restaurants, coffee shops, and bars. The apartment has easy access to Regents Park, Oxford Street (and Soho overall), Tottenham Court Road, the British Museum, Great Portland and Great Titchfield Streets. It could not be better located in Central London.
The ground-floor apartment itself is located on a trendy but not highly trafficked. street. As with much of Fitzrovia right now (there is a bit of a building renaissance happening), there is a large construction site across the way so if you're visiting soon there is some construction noise/jackhammering that can be heard throughout the apartment during "business hours".
Amenities are utilitarian but perfectly nice - helpful to have both a dishwasher and a washer in the apartment. A weekly cleaner was an incredible touch that made me feel a bit like I was living in a hotel. The hosts are extremely kind and responsive - and made me feel super comfortable during my month-long stay.
Overall, a great place in London. I would definitely stay again! :)
