Great stay in our trip to Paris. Beautiful building with a courtyard and great location in the Marais district. Perfect studio for 2 adults and 2 kids. Carole was very responsive and a great host.
There are a lot of restaurants nearby and there is a market down the street for any groceries. Marche des Enfant Rouge is a 10 minute walk and a great place to grab lunch.
We didn't use the Metro and walked to the sites which were 10 to 30 minutes by foot. It's a great way to experience Paris if you have the energy. We took a taxi back (usually under 15 euro) when the kids got tired or were further out.
Only downside is there no air conditioning. The weather was great during our stay, so it wasn't a problem. We could sleep with the windows open, but might have been difficult during the heat wave the prior week.
