Me and my partner spent 3 nights in Paris and couldn't have picked a better place to stay. The duplex is very clean and has everything you might possibly need to feel at home. My partner is 6'3 so he struggled with the low ceilings but I loved the cosy feel to the place.
Pilar was the perfect host and welcomed us with warmth and lovely gestures such as a fresh baguette and sundries. Great communication, she went out of her way to explain the local area to us and made many useful recommendations. She even provided me with paracetamol on one of the days I was feeling unwell, which saved my headache (thank you!).
Le Marais itself was picturesque, not too 'touristy' and had great transport links to everything in Paris. We even had time to visit Monmartre, which was only about 25mins away from Pilar's place and well worth a trip!
Overall, I would highly recommend staying here, you will not regret it, as you will be in the heart of everything and get a more of an experience of local life. P.s There is a great natural wine shop called Divvino around the corner x
