Avoid this place at all cost until you can be assured construction inside the apartment hallways, entrance and elevator is complete and the apartment had been THOROUGHLY cleaned of construction dust. Although we were advised in the listing that there was construction in the building entrance, we were shocked and angered to discover that there was fine construction dust covering every surface inside the first (US 2nd) floor apartment. This included on the furniture, floors, counters, linens and bath towels. Not long after arriving we could feel and taste the gritty dust in our mouths. Sitting on the chairs we picked up gray plaster-like dust on our dark clothing.
The host who let us into the apartment told us the place had been cleaned a day or two earlier but from a practical stand point that seems hard to believe. (Moreover, we found dirty, smelly dishes left in the dishwasher.) If it is true, there must have been an intense and rapid leak into this apartment for it to get so filthy so fast.
The location in St Germain is convenient to many shops in a nice Paris neighborhood and close to the St Placide Metro station. We enjoyed being in this part of town, but staying in the dirty conditions we encountered was intolerable.
