Raul offers a second bedroom in his own lovely apartment, with shared bathroom and kitchen facilities. Its location is a bit of a walk from the Metro station (I found Gambetta closest), but there are bus stops right outside for 3 routes. Research where you want to go to work out which is best for you. I chose it specifically for its proximity to Père Lachaise Cemetery, where I spent a morning wandering around. And it’s just about the best value AirB&B I found in Paris! Incidentally, Raul is a very talented actor and theatre director, and I was fortunate to see him perform in a classic French play which he directed.
