We are considering accommodations near Rue du Lyon & Avenue Ledru-Rollin in Paris. We love to walk and we are wondering if the neighborhood is a safe neighbourhood and if the avenue that crosses the river from there is good for walking? The area looks very conveniently located but we are not very familiar with Paris after only one visit years ago. I have read that Le Marais and St. Germain areas are popular and this area appears to be not too far from them. I look forward to any comments. Thank you!
