My girlfriend and I stayed here for 9 nights during New Years time and Christian’s place was great in terms of location, comfort and amenities. We were close to many major attractions and a walk or quick metro away from everywhere else that we wanted to visit. The kitchen was well-equipped and we were able to cook a lot of meals (very useful in Paris) or enjoy a nice cup of coffee. The place itself was spacious for a studio apartment and very well decorated, it felt like we were living in someone’s home (probably because we were).
Check-in experience was good, given that we arrived 3 hours early (without any notice) and the bnb sitter came as soon as he can to let us in.
All in all, I would strongly recommend Christian’s place for any couple visiting Paris!
