This is was just perfect. If you need to really experience Paris, I suggest you go for this apartment. (For 2 people)
Carole sent Laurent to help me check in. Even though my check in time was 3 pm and there was previous residents, Laurent managed to help me check in by 11 am. The apartment was spotless and tidy. Clean sheets with spare in the closet. Towels were clean in the dryer.
The apartment is in a strategic area. Odèon is one of the best places to be. The metro was just outside, making commuting very easy and cheap. A few blocks up was the Siene and a few blocks down was jardin du Luxembourg. The building was secure and clean.
Definitely my first option when I come back to visit again.
