Thomas' apartment is very near the Metro and has easy access from the Gard du Nord and the RER from the airport. You can walk to and from Montmatre, which has a number of lovely places to eat. The apartment was quiet at night and it was very comfortable. There were no issues with noise or anything else. On the whole, the neighborhood is safe but one should be aware that during evening rush hour, there are pickpockets about. There are no issues during the day or after rush hour. One just needs to be vigilant.
