Me and my brother had a great time staying with Guillaume, we could do our own thing because we had the house key and when we returned home we had lovely conversations about what we did that day or our lives. The location is really good, there's a lot to do in the neighborhood and there are a lot of nice bistro's you can go to. I would really recommend staying with Guillaume and he can give some good advice where to go in Paris and help you with what you are looking for.
