We (3 adults) had such a lovely time at Yosr's place, the 11th arrondissement is so vibrant and less touristy. Yosr responded to all my questions super quickly and is such a sweet person. The sofa bed is the most comfortable convertible bed I've ever slept on, the space is large and bright, I'd recommend staying here. The only thing to note is that it's on the top floor without an elevator but it's not a big deal as you get used to it very quickly.
