While I never met Margot--she was very prompt in responding to my messages and sent me all the information I needed. The apartment is cute, clean, and located in a great neighborhood.
As others have noted, the apartment is above an event space. Margot informed me that there would be an event on the evening of our stay and it would end promptly at 11pm. The event did end on time. The apartment faces the courtyard that the event space uses, so it got pretty noisy when the event was happening.

Overall, we would probably stay again (even if there was an event).
