If you don't like to walk, Moscow won't like you. This city has no tolerance for people who can't walk. If you don't want to walk, you can do it, but I think it will be very expensive - taxis, or your own car and parking. Sure the metro is unbeatable, the buses are great, but how about walking to the metro or bus stop? Or to the corner grocery that is two blocks away? Or up and down the stairs everywhere. This city likes to keep its citizens in good shape.
I thought I was getting better shape, but my feet and legs had forgotten what a punishment this pavement is! Ow.
Huffing and puffing, yours truly, Mark.
