Unfortunately there is a significant mold issue in the main living room, which was known but was not communicated to us prior to arriving. My husband is allergic to mold, and we were traveling with a small baby who we could not allow to sleep in that environment (and yes, Slim knew we were traveling with a baby, and about the mold issue prior to our arrival). We wound up leaving our stay in Paris early, with no offer of compensation.
Once the mold is fixed this will be a good place, with a positively great location and a bathroom that is palatial by Paris standards. But till then, we cannot recommend anyone stay here for health and safety reasons.
