So my friends are staying right on Leicester Square, very close to the dark blue, black, and brown lines. I will be meeting up with the m, so ideally I want to be either close or easily accessible. I'm going to let Priceline choose a hotel for me, I just need to give it the neighborhoods I want. What is going to be best, in terms of ensuring easy connection? I figured Soho - Mayfair the best choice safe, now what about Westminster? On the map, it doesn't look like the dark blue/black/brown tube lines go there. Is it connected well by buses? What about Chelsea - Knightsbridge? I want about a 20-30 min distance by walk/bus/tube to Leicester Square, and also preferably near other attractions (so we can use my hotel as a meeting point rather than theirs).

I can't spend days researching neighborhoods, learning bus routes, and choosing a hotel (the way I would for a longer trip), so your help will be very appreciated.
