I would HIGHLY recommend staying here if you have a chance to - the location is so central to the metro, Le Bon Marche, and dozens of adorable smaller boutique stores in a beautiful setting of preserved Parisian architecture. There is a boulangerie and grocer just around the corner and the walk to the metro is only 3 minutes to Sevres Metro Station.
The studio itself is adorable and modern with Aesop amenities and is extremely cosy thanks to the addition of a roaring fireplace (controlled electronically) and a steaming hot water system which has excellent pressure. I feel the cold very easily so this was the main selling point for me. There is a hairdryer as well as a washing machine-dryer which is super helpful instead of wasting time at the laundrette! I did not use the kitchenette much for cooking but there are cooking amenities for those wishing to stay at home and cook. Pierre provides a decadent tea as well as a nespresso machine for your morning caffeine fix. There are two skylights - one above the bed and one above the dining area for your use and adjustment as you please.
The location is within the second courtyard (so there is a first courtyard separating you from the street) so it is extremely quiet, and all of the residents are very quiet as well. Also, the area feels very safe for a single female walking around the streets. There are many bistros and brassieres and cafes dotted throughout the neighbourhood to suit your taste.
I met Pierre and Isabelle on the first day and they were extremely warm and helpful and made me feel so welcome after a long trip from Australia.
I will be recommending Pierre's place to all of my colleagues who visit Paris and would definitely be my first choice to return to Paris - thank you so much to Pierre and Isabelle who made the stay so lovely!
