Olga's apartment is delightful, tastefully decorated and clean. We especially love the large windows that open up to the boulevard. Also, the shower is luxurious--perfect temp and pressure, roomy, great towels and even a towel warmer.
The location is excellent. Walking distance to all the major attractions or 5 minutes to metro. The St. Germain area is full of cafes, shops and little alleys to explore.
Agree with taking shared taxi (€40) or cab (€50) from airport as previous review mentioned.
