Maelle's place was absolutely beautiful and had everything someone would need for a stay in paris. The building was kept cool, the apartment space was very cute and clean, and Maelle kept in great touch if you needed anything.
The apartment is up 4 flights of steep stairs, so if you have large bags you might run into some trouble there. Otherwise, it is a fantastic little space for one or two people. Very close to Gare du Nord and Gare de l'est is about a 10 minute walk.
