没有美国大城市那样的治安问题。网上找的伦敦旅游住宿推荐，总结得不错，见内

The West End (Covent Garden, Soho, Leicester Square, Oxford Street, Mayfair) is a very central district with most of London’s theatres, top art galleries, excellent, varied dining for all budgets and much of London’s nightlife. 4-star and 5-star hotels dominate, with some midrange bargains. It’s easy to walk around and handy public transport connections to other parts of London.  This area is excellent for families staying in London.

家里人口多的话可以找市区的Air B&B，出门打车也方便的。

伦敦中心地段住宿贵。如果想省银子，可以找远点的地铁沿线的旅馆。我去的时候住朋友家离市中心很远，地铁高峰时特挤，挤得关不上门那种。不过那是老黄历，现在不知道怎么样了。
