My 19 year old daughter and I want to spend 5 days in London as part of a 15 day trip to Paris, London and Edinburgh with 5 days in each city. My daughter loves art, theatre and museums. I love the history of Great Britain, theatre and museums too. Can I get recommendations for where to stay that is SAFE, centrally located, easy to get to and is good for a single mom on a budget? Any other advice you think will help me is appreciated.
