Hotel Jardins du Luxembourg
http://www.travel-in-paris.com/jardi...rg/english.htm is my favorite 3-star boutique hotel in Paris. In a lot of ways it should be 4-star. But the best thing is the price is always €135 no matter when you book it. The neighborhood in the 5th is great and they have Wi-Fi in rooms on the 4th and 5th floors.
