We had a great experience staying at Berenice's flat. She and Jonathan were out of town but we were taken care of by their charming, welcoming, and very willing and helpful neighbor Christine (who shared funny jokes, handwritten notes, and tips for navigating Paris)! All along the way, Berenice was highly communicative via messaging to help liaise and clarify details when needed.
The room itself was larger than I expected -- an ideal space for two people, and spacious for one. The in-room shower/sink was really convenient. All amenities are exactly as listed: ample toiletries, plenty of storage space in the wardrobe, extra towels and linens, tea and hot water kettle for the morning. We also appreciated having access to the fridge to store some groceries (but no kitchen access beyond that).
Overall, Berenice's place is an excellent home base for any trip to Paris. The location in 9th is fantastic. We walked or accessed the many nearby bus/Metro lines to get to our destinations throughout the city. We'll definitely stay here when we come back to Paris.
