Maria was a superb host, and the apartment was beautiful. Very spacious and comfortable, with well-equipped kitchen and bathroom. It was very near the metro, but the neighborhood itself is a charming place to take a stroll or find a cafe. It is a bit quieter and more residential, but certainly still lively.
Maria went out of her way to be helpful, in English or French. She is also full of recommendations for things to do and see, in Paris. I especially appreciated her making soup and sharing a film when I got a stomach flu. Being ill isn't a fun way to end your European trip, but she made it bareable :).
