Beige-simple, without unnecessary flourish, but extremely well-maintained, the Americana is a strong value in a neighborhood besieged by rising rates. Robert, the chatty and opinionated longtime manager, is exactly the kind of authority on London (and on everything, really) that you wish to encounter behind a B&B desk. Room 124, a twin, is slightly larger than the others, but all have showers, tiny TVs, a safe, and plenty of light. Although it’s comprised of two conjoined town houses, there’s a wee lift, and it’s also very near Regent’s Park and, unusually, steps away from a launderette. Rates can go even lower in winter or if you agree to stay for longer than three nights.
