I recommend staying at Marion's place. It was tiny, but clean and worked well for 2 people. The bed was comfortable which is always something I value highly.
It was easy to get around via the metro or uber. Marion was communicative, friendly and easy to work with. I was surprised that there was a shower, but rather a tiny tub. (For an American this was surprising but might be common in France/Europe?) I recommend eating at Pimpin cafe just a few minutes walk away.
