Our family of three stayed at Miriam's place for five nights. We had agreed with Miriam earlier that her daughter would be waiting for us at the apartment upon our arrival around 2pm. But when we arrived there, her daughter was not there and not replying our messages. We then called Miriam, she didn't know what was going on and after hung up the phone, she didn't call us back either only. So we had to call her again, she apologized that her daughter could not come because of an urgent family issue, and she could only come back after 5pm because she was out of Paris at the moment. We were a bit shocked and upset at that moment that we would need to wait a few more hours while keeping our larges luggages with us before we could enter the apartment. Yet, Miriam sent one of her friend to meet and show us around. However, as we couldn't enter the apartment, we needed a place to keep our luggages. Luckily, Miriam managed to ask one of her neighborhood to help us to keep the luggages in his apartment. But we had to wait till very late to get back our luggages because her neighborhood was out during the evening. It was 5:30pm, Miriam finally made her way back to the apartment to meet us. I had to say the check in arrangement was disappointing and wasted many hours of our first day in Paris, but afterall Miriam was very nice to our family though.
To add one more thing to note is that the place was too small for three adults. We had to make way for each other to passing by and there was even not enough space to open two luggages at the same time. If you are looking a place with some space of one's own for three adults, I wouldn't suggest it.
