Concierge.com's insider take:

This guesthouse is something of a well-kept secret hidden away in trendy Marylebone, north of Oxford Street. It's the brainchild of Amy Wear and Gail Downey, former models turned knitwear designers who converted the spacious three-story Victorian townhouse above their boutique into a six-room hotel. Each comfy bedroom is individually designed in a bohemian take on Regency style. Four rooms have en suite baths; the other two share a bathroom on the landing, which keeps costs ridiculously cheap for this neighborhood ($144 en suite, $134 with shared bathroom). On your doorstep are Regent's Park, Lord's Cricket Ground, and Madame Tussauds, as well as many excellent boutiques. Guests can try the potluck (soup or stew), made nightly by Downey's wonderful housekeeper Titiek, and in the morning a full English or continental breakfast is served in the dining room. At street level, the Weardowney boutique is a trove of beautifully handcrafted knitwear and vintage clothing and shoes—a tempting place to spend the cash you've saved by staying here.
