Good security at flat but several issues. First we arrived on a day that was 100 degrees in Paris. We knew there was no air conditioning due to the description of the apartment. However, there were no fans in the apartment and the bedroom window only opened 3 inches. We were able to get a fan at a local department store, but we didn't get to sleep till after midnight. The bathroom also has a horrible problem with mildrew due to lack of ventilation. Would be a great flat with a little TLC. Good security and location to the metro. However the apartment seems more set for 20-somethings looking a place to sleep after a night of clubbing rather then a comfortable place to stay for a family of 5 visiting Paris.
