It was a perfect place to stay. You can find anything in her flat. Good location, kind host, clean room, hot water. It's just in front of metro station and quite close to Montparnass tower, it means you can use many bus lines including the buses to the airports in paris, night buses)
In the building, there's such a nice Italian restaurant, serving real Italian food and coffee with resonable price. (It was exactly same as Italian dishes when I visited Italy last year)
Ralda was kind and lovely, it seems like she keeps the flat clean and tidy.
