Event though Charlies sister let us in the apparmente and we havent seen Charlie, the Check-In went very well and he called to ask if everything was okay. He was very nice, answerd very fast and I would highly reccomend him. The flat (room) was very tiny but it had everything we needed. The location is just perfect, near the Gare du Nord and you can walk to Louvre, Notre Dam and so on. There is also a metro station just around the corner. We really enjoyed our stay at Charlies room. :)
