Our apartment literally sits on one end of the courtyard outside the Centre Pompidou (Paris's modern art museum). The feel of the apartment area isn't as residential as, say where we stayed in the Latin Quarter in 2007, but it's a good cross between residential and I guess tourist. It reminds me of the location my Dad's former apartment in Manhattan (West 55th street), where there were plenty of residential buildings but because it was also midtown, plenty of hotels in the vicinity.
As Mom said our first night, you won't starve in this neighborhood. Within a block on either side of the apartment you'll find two boulangerie, two markets, a dozen cafes, three or four charcuterie (sp), two fruit stands, a movie theatre (actually right below the apartment), a few creperie, Amorino gelato, several Japanese/Chinese Restaurants, a cous cous place, a couple of Lebanese take-outs and I can't even recall what else.
There are also tourist "stands" in front of the Pompideu with tee shirts, and all sorts of chotchkeys, clothing stores, sporting good stores, pharmacies, banks, video stores, and the mall at Les Halle is a five minute walk away etc.
