What a great stay we had at Pierre's place. This was a family trip that included my wife, my 18 month old son, my mom and her husband. The place fit us perfectly as we needed 3 rooms. 2 of the rooms had queen/double beds and 1 had 2 twins. The room with 2 twins is the one we used to set up the baby cot provided by Pierre. I found the bed to be rather comfortable and slept well the entire trip.
The rest of the place was as pictured. It has a single bathroom with a tub and then two water closets with toilets and small sinks. The separate water closets with sinks and mirrors were very useful with 4 adults needing to get ready to go in the morning or go to bed at night. The kitchen had plenty of pots and pans and plates. We only used the appliances to reheat some takeout meals but you could cook some big meals if you wanted to.
Check in was easy and we were able to drop our bags while the cleaning crew was there as our flights and transfer got us in earlier than 2 pm. But we were able to walk up to Rue Mouffetard and get lunch.
The location is great too. You are short walk from Place Monge and Cardinal Lemoine Metro stops, which are 2 different lines. And if you want to take the bus, which we find easier with a stroller, there are many bus lines within a short walk of the place. There are a lot of options to eat on Rue Mouffetard and places to get a drink on Place de la Contrescarpe just a short walk from the place. We also found a great playground less than a 5 minute walk away for our son.
One thing that I had not seen on an airbnb before was an optional cleaning fee. When you book there is no cleaning fee added on and you can either clean the place yourself or contact Pierre to have cleaners come for a fee. The fee for us was 70 euro. I don't know if that fee changes based on number of days or people or is a standard fee. But if you don't clean and don't set up a cleaning before you leave you could be charged up to 120 euro from your security deposit.
This would be my first place to look at when I came back to Paris with a family.
