Lux is very welcoming, she is a nice host, caring and available; my train arrived indeed at 12h and the room was available from 18h only. Lux agreed to let me come earlier than planned as she was home. I also appreciated I was allowed to use her kitchen to make supper. I had a great time in her house.
Even if the quarter seems to be not so close from the center, it's very easy to reach it. Lux's house is only 5 minutes walk from the nearest underground station. The neighborhood is reassuring ; I felt secure to come back alone in the evening. And maybe I'll come back one day, be sure I would recommend Lux's place to my friend.
