We really enjoyed our stay in Charlotte's apartment. It is a very individual place with lots of character. Everything you could need is within reach - the kitchen is fully equipped, there's a nice quiet courtyard out the back (which although shared with others, is not open to the street). Local amenities are abundant: there are a wealth of grocery stores, bakeries etc within a short walking distance. Public transport links are as close to perfect as you will find, which means you can be in central Paris in less than 30 minutes.
We would not hesitate to recommend Charlotte's apartment to individuals, or couples with a child (but not more than one of them). We were sad when our time came to go home, and would return in a heartbeat!
