The bon bon is a beautiful, cozy gem in the heart of the Marais. We had a wonderful time there. It's a great neighborhood, perfect for wandering around in, shopping, and relaxing in the squares. The shower is very small (like the rest of the apartment) so if you're on the bigger side, you'd probably prefer something else. The church courtyard has recently been converted to an outdoor café area, so we had to pull down the blinds completely when we were dressing. Probably a good idea anyway.
We left the windows open to the little alleyway and enjoyed the thunderstorms as they passed through.
