The apartment was light and airy, easily accessible, in a wonderfully diverse non-touristic neighborhood. Around the corner is a bus stop on a major route so that one can be at Montparnasse station in minutes or on the Ile de la Cite within 20-25 mins. There are two metro stations within easy walking (10-15 mins at most) distance.
The options for food are too many to recount: bistro cuisine, Thai, Japanese, Chinese, pizza, Italian, sushi with local grocers and take out places providing other options, as well as, 2 excellent boulangerie-patisseries within a block. I believe I counted 5 cafes within a 3-5 min walk.
In other words it is a real neighborhood where real Parisians live and work. Mme. Berg provided me with maps and timetables and books about the neighborhood and places to go. She also gave me information about one of my favorite past-times: flea market shopping. Her apartment is mere blocks from one of Paris' major flea markets. I was in heaven. She made me feel welcome and provided me access to a Paris that is both rare and precious.
