We will be visiting Lyon for the first time in late September. Can anyone comment on whether it would be preferable to stay on the Rue Mercière in the 1st, Rue Chartreux in the 1st or Rue du Boeuf in Vieux Lyon (the 5th, I think?). We are in our 50s and able to walk to get around. Just wondering if one place or another would require use of public transport or could we get to major sights/museums/restaurants/parks on foot from each of these. Finally, we would like to have quiet at night. Merci!
