I would like to visit the Hilton Andaz hotel to see the old building's architecture - expect I'll also take some refreshment there-I'm on holiday! I will be at St. Paul's cathedral when I start out for Liverpool Street. I've looked at the TFL.com site, and I can't understand which is the best tube stop for me to arrive at the Andaz hotel. Is there a tube stop at Liverpool Street? I understand the hotel is adjacent the train station. Thank you.
