16, rue du Parc Royal flat

75003 PARIS
3rd arrondissement (the last 2 digits of the Paris zip codes denote one of the 20 arrondissements)

The following information is from HERE:

Arrondissement 3 - Temple

Another small arrondissement; it contains the northern part of the historic Marais district. The Conservatoire National des Arts et Métiers (National Conservatory of Arts and Crafts), the Picasso Museum and the Carnavalet Museum - devoted to the history of Paris - are located here.

The city of Paris is divided in 20 arrondissements. The first one is in the center, the following ones spiral outwards in a clock-wise direction. Most of the famous tourist attractions can be found in one of the central 8 arrondissements.
The arrondissements are encircled by the périphérique, a ring highway. Outside the périphérique are the banlieues, the suburbs of Paris.

The location of my flat was within walking distance of retails shops, cafes, parks, monuments, fountains, historical buildings, bridges, and the Seine River.  Oh, and the Metro!
