Sandra and Bruno were truly wonderful hosts. They were always keen on taking care of us, and offered help and advice whenever possible. Sandra even gave us advice concerning future trips outside of Paris based on her travel experiences. We spent lots of time in the common space with Sandra and Bruno, and they even shared meals and drinks with us. We were always comfortable in their company and always had a good time with them.
As for the apartment, it's location is great, we were able to walk or take a quick subway ride to any of the main attractions. The neighbourhood is also very cool as the streets are flooded with little shops, specialty food stores, and cafés everywhere. Everything in the apartment is very clean, and the kitchen and bathroom had everything we needed. The bedroom looks small, but my girlfriend and I had five fantastic sleeps in that bed, even though we are used to sharing a North American queen size.
I cannot think of a single negative aspect of our stay, it was just great, I would highly recommend staying with Sandra and Bruno.
