Amazing location. You really can see Notre Dame from the apartment. Just a short walk to the metro and hundreds of restaurants. I couldn't ask for a better location.
The apartment was nice. The bedroom is a bit small so the bed is surrounded by 3 walls which makes getting in/out of bed a little awkward if there are two of you. Other than that, the apartment was perfect. We forgot there was a lift because it was hidden behind a door so we spent the first 2 days hiking up and down 3 floors. Once we found the lift, we used it but it is so tiny 2 ppl can barely squeeze in.
I would definitely stay here again if visiting Paris.
