The best thing is the host!!! Edouard response very quickly to your question and problem. He kindly let us early check in around 1.30pm. Self check in details via message very clearly.
Apartment as shown in pictures. Locate 200 m from Poissonniere station and on the ground floor. Wifi works well. But be aware about master bed as pervious review - it‘s the raised bed with narrow and steep stairs, not suitable for elderly or who are not taller than 160 cm., but you can use sofa bed instead.
I highly recommend Edouard’s apartment esp. who travel from Gare du Nord/Gare de l’Est - distance only 500-700 m from this 2 main station.
