Great location, 20min walk to Eiffel tower, 30 walk to catacombs, 30 min walk to Louvre. It's located on the left bank of Paris so either catch a train & metro to there or grab a fix price taxi from the Airport. From Orly it cost us €30 taxi, vs Uber quote of €40.
Nice area, lots of nearby places to eat and drink. Apartment is located on the 4th floor without a lift, which was a little tiring after a long day but it was very secure and safe.
Apartment had a plug in fan which was a life saver as at night the room was very warm, but opening a window was just as effective with the cool evening Paris breeze.
Metro is about 5mins walk from the apartment and costs around €1.90 for a single upto 1.5 hours which was a bargain.
