Paris is really expensive so Marie’s place is really affordable. There are a few shortcomings but Marie is an amazing host and it made up for anything lacking (not anything significant to be honest)
Location - very accessible to metro and buses! Food at your doorstep, two convenient store (Franpix) right outside. On Friday morning there’s also a local market where you can get amazing fresh fruits!
Place - it is a small studio, but definitely enough for two persons! The door can be a bit tricky but it’s nothing major. My mom and i stayed at the flat for 3 nights, she had the couch while I had the bed. The bed upstairs is actually really comfortable, just make sure you are fully awake before coming down:) in general, it is a lovely decorated place!
