I absolutely loved staying at Valérie and Robert's apartment. The space is so lovely and unique, a great respite from the busy streets of Paris! I was there during a particularly hot week, and the apartment has AC, which was truly a life saver. The kitchen was well stocked for cooking and there were several great markets- both supermarkets and open-air markets- nearby. Montparnasse is a very charming area of Paris and I really liked being in a neighborhood a bit away from the overwhelm of the Notre Dame area, but close enough that a pleasant 25-30 minute walk had me at Shakespeare and Company, and 5 minutes more in the Marais. Valérie was very quick to respond to all of my messages and had plenty of recommendations on markets, gyms, etc. I would highly recommend staying here, I hope to return soon!
