The flat is in the center of Paris, i always walked to every spot i wanted to see and never had to use the subway (i walked 20 km a day, so the ways are sometimes a bit longer to some spots, but if you want, you can reach everything by feet)! Lucia and Wladimir are very nice and so helpful and leave you space for yourself, if you want. I really enjoyed the stay and can highly recommend to stay at their Airbnb!
