I had a very enjoyable stay at Lou's place for around a week. The location was great, at walking distance from the Eiffel tower, and very close to a variety of stores and bakeries.
The place had ample space for me and two more people. I slept in the sofa bed which was very comfortable, and combined with a quiet neighborhood, I slept very well.
Lou was also very responsive and made the process of check in quite easy.
