I stayed for 3 1/2 months at Ludovic’s place and had one of the best times. There is nothing I can complain about: the communication and service were outstanding! I had one or two problems with the lighting and he sent a handyman within hours to fix it.
Location is also amazing, located outside of Le Marais, not touristy and absolutely perfect for a long-time stay. Everything you need for an everyday life is right around the corner: from supermarkets, bakeries (best bakery of Paris: Tout Autour Du Pain) to cafes/ restaurants. There are three metro stations close by. Longest is around 7 minutes away, however, everything can be reached by foot very easily. Overall, I would definitely come back, as this apartment will always have a special place in my heart.
