We loved our stay at Oliver's place. The apartment is light and bright and had everything we needed. It is really a beautiful space - the photos don't do it justice!
The apartment is walking distance to the Louve, Notre Dame, and lots of great cafes and restaurants. It's also right next to a major Metro station, so it's easy to get anywhere in Paris. There is a lively cafe across the street, which was excellent for people watching from the balcony.
We had a great stay, and would enthusiastically recommend Oliver's place to anyone.
