Sebastian was not able to meet us for check in but emailed us detailed instructions which were easy to follow, check in was very easy. The apartment is exactly as described and very clean. All the essentials and more are there. The apartment is comfortable, roomy and quiet. You dont get noise from the neighbors or the businesses way down below. With the windows open you will get noise from the traffic below. The location of the apartment is fantastic for exploring Paris and Le Marais is the best place to stay in Paris IMO, there are lots of great cafés, supermarkets and shops. We walked to a lot of places, we also used the metro on hot days. The apartment does get warm on hot days (30plus degrees C for us) but Sebastian has excellent fans. He even has a evaporative cooler but we didn't see the need to use that. Sebastian was easy to contact, but he has manuals for everything so you shouldn't have the need to contact him. Sebastian's place is a great place to stay!
