My husband and I had the best 1/2 day with Susan to Windsor Castle, our only regret was we should have done this the first day as Susan was the perfect host and knows everthing there is to know about London. She shared the most interesting stories ( you won't get these on big tours) was personable, professional, funny and an expert in all things "Royal". Gren Tours was easy to book, confirmation emails back and forth and very helpful with suggestions. We ended up with the perfect guide, Susan! The only way to see London is with Gren Tours.
