The apartment was nice and cozy. Lila was friendly and flexible with check-in/check-out timing. Unfortunately, immediately after Lila left (while we were shifting our luggage up to 6th floor (to note: only spiral staircase available-this was not mentioned in the original listing)), we were unable to unlock the door due to faulty key/lock system on the apartment door. My phone was left in the apartment hence we had to engage the neighbor's help to call Lila (we couldn't speak French, and they couldn't speak English-it was tough). Long story short, we spent few hours trying to unlock the door, activating various neighbors to help (thank goodness they were friendly), waiting for Lila to return back (she was pretty reluctant to return at first when we were desperate to contact her to help, she did in the end after an hour later). This totally concluded our pathetic last night in Paris. We couldn't grab a proper dinner or do any last minute shopping as planned. As much as I would like to leave a positive feedback, it was a terrible and frustrating night for us due to the hiccup :(
