Haas is awesome very quick to respond. Though its not central london but I would totally recommend it. Its 30 sec from kilburn station close to super market etc. The space might get bit tight for 4 people (we were 2 adults and 2 kids) but still manageable. Very thoughtfully done. Only other suggestion i have is having some additional plugs for usb charging might help international travelers. The deli below is fabulous esp with lots of veg. Choices.
