If you want something affordable, close to the metro and walking distance to some great restaurants. There are three sets of locked doors to go through with combination codes for each. We thought of this as a fun game, however if you can’t figure to out the host will guide you through it. She was very patient and helpful, she checked to make sure things were ok. The unit is clean, comfortable and quiet. The neighborhood seemed safe as we were out all night and never had any problems. Just steps from the metro makes it very easy to travel the city and save money on taxis. Amazing local experience in Paris.
