Hi Mrs. Spoons.
In addition to the above, I thought you might like to look at the following information I have found in answer to your request. I have been unable to find the distance between the two apartment complexes, but as Peggy, Laz and Tina have already said, they are both in the Canal d'amour area. If you contact your Tour Operator/Travel Agent and asked to see "The Gazetter" (TOs/TAs Bible), they should be able from this give you the distance/location of the two apartments.
Both apartments are highly rated, and some very good reviews, comments and information are given on the following pages.

Hope this helps in someway. Do have a great holidays, as we know you will, and let us know how it was with your own comments, photos, etc.
