The 42-room upscale Marble Arch by Montcalm is the smaller sister property of the luxurious Montcalm Hotel located across the street. Housed in a small townhouse, the modern boutique hotel offers an equally luxurious experience, though at slightly lower rates and with fewer in-house amenities (guests can use the Montcalm’s spa, fitness center, pool, and restaurants). The contemporary rooms are small but elegantly appointed with scent machines and large flat-screen TVs, and free Wi-Fi, bottled water, and fruit. Breakfast, served in a pleasant sunlit dining room, is available for an additional fee. The central location is close to the tube station and is a short walk to Oxford Street, though there are many other hotels in the area and it’s worth comparing rates.
