Lionel and his apartment are both lovely! The apartment is elegant and spacious for a one bedroom place. Lionel is incredibly communicative, and he provides excellent recommendations for places to see, special events, and restaurants in his neighborhood and others.
There are 3 metro stops 5 minutes from his place, so it is easy to get around Paris.
The bedroom is at the back of the apartment and has blackout curtains, so you can have a restful night. If you sleep in the front room or loft, however, you will probably need ear plugs because the street can be noisy at times.
It is a great value for a Paris apartment.
