My husband and I stayed at Gret's for a few days at the end of our European tour. We had a lot of musical equipment and baggage which made the location of Gret's apartment a huge bonus. We took a taxi from the train station which was approximately 20 minutes to get to her place. It is right on the street level, an old art gallery converted into a beautiful space, and easy to navigate with luggage. Gret had a nice bottle of wine waiting for us, and the espresso machine in the apartment was a plus in the mornings. Amazing king sized bed, large walk-in-shower, and in a quiet street just a block away from all the action. Walking distance to everything you could want and need in the Marais. Picasso museum is right around the corner. The museum is closed on Monday's now instead of Tuesday's if you are planning to go to the museum. I had issues ordering a taxi the night before we had to leave, and she responded late in the evening to order the taxi for us. She is a wonderful host and her apartment is a GEM!
