We stayed five nights at the Hôtel Le Sénat and loved it. The staff is very accommodating and the hotel itself is modern and lovely. Our room, although on the smallish side as are many in Europe, was comfortable and looked out onto the Rue de Vaugirard. The location is perfect; a few steps from the Luxembourg Gardens, the Odéan theater, a five-minute walk to St. Germain and just 5-10 minutes from the Seine.
