My husband and I are doing a quick 3 day/2-night visit to London at the end of the year. It's been over a decade since either of us have been, so we'll be doing touristy things - like 1 or 2 museums, and shopping. We don't need a suite, so entry level rooms are fine. Unlikely to need any concierge services. One caveat is that we're arriving at LHR on Boxing Day morning, so we will have limited public transit options into London (Yes, I am aware museums are closed on Boxing Day itself). The hotels in our budget are: Baglioni, Shangri La, Beaumont, Rosewood, Corinthia, Savoy, Goring, and Langham. Suggestions?

• Shangri La is probably out because of its location.
• One top choice was the Savoy, but since reading this thread and because we're the stereotypical California casual types, I feel like it might get awkward.
• Baglioni is the cheapest by far but I've only seen one (very negative) comment about it here. Out of curiosity, can someone elaborate on what's so bad about it?
• Right now, the Rosewood seems like best option for us (even though this thread seems meh on it) because it's 1) short walk from a Piccadilly line tube stop (to get there from airport) 2) walking distance to British Museum and Chinatown (better chance of restaurants being open on Boxing Day) 3) and relatively bigger entry level rooms.
