It's hard to imagine a better location as a base for sightseeing in Paris! Here, you're only a few minutes walk from the Eiffel Tower with easy access to the Metro and RER. There's a lovely boulangerie down the street to get pastries and coffee, and a grocery store and several restaurants within a couple of blocks.
The space is well appointed and had a very modern feel to it. More importantly, it was roomy enough for five of us. Although the space is on the ground floor, there really isn't much noise from the street or the nearby businesses.
