My husband and I stayed in the La Défense area during our trip to Paris in November 2016, and I must say I am happy with our choice for the ease of accessibility and the breath of fresh air from tourist congestion.
La Défense is not your typical tourist destination in Paris. It is where they keep all of the unsightly corporate buildings (except Montparnasse Tower), and where French people (both Parisians and suburban) go to work. It is a modern corporate park. But, it seems that the French figured out a great way to make an unsightly corporate park easy on the eyes. You can walk along the long boardwalk all the way up to the Grand Arch and find colors, shapes, and structures which will surprise and delight you.
During normal business hours, La Défense bustles with non-tourists. And if you know anything about Paris, you are aware that at most tourist destinations, you will find masses of people cramming in lines and solicitors desperately trying to harass them to buy tchotchkes. This is not the case in La Défense. My husband and I were happy to start and end our days in peace and quiet, away from all of the mayhem.
If you are not staying at La Défense but are visiting Paris in the winter season, I recommend taking the RER red line or the yellow metro line #1 to La Grande Arche stop, where you will encounter "Le Marché de Noël" (open Christmas markets) between November 23 - Christmas. You can find really good and reasonably priced local or Swiss cuisine as well as holiday goodies, ranging from smoked meats to local cheeses, wines, winter clothing, and tchotchkes. There is also a huge mall called "Le Quatre Temps" located next to the arch.
Oh, and re: the Arch, you cannot climb it. There are a few steps which will allow you to gain some elevation. But the Arch itself is actually an office building.
