I assume you're asking about Choice hotels, because this is the Choice forum. I hate to state the obvious, but sometimes you never know.

Anyhow - the only place in Paris where I have personal experience is the Clarion Collection Opera Pavillon, which I reviewed here.

To reiterate, it was clean and comfortable and provides breakfast and afternoon snacks every day. The Metro stops are a short walk away, one in either direction. Place du Clichy is a quite busy semi-tourist area with lots of shops, eateries, etc. Several tourist attractions are walkable, but the Metro gets you anywhere.

Paris has various cards similar to London's Oyster card (for Metro use), but they usually come bundled with various museum entries, which you may or may not need/want. I'd recommend just getting carnets of tickets - save on 'volume' and you'll pay for nothing you won't use.

We never took the bus in Paris, so I can't comment on that. The bus/taxi situation in Paris is not like London, but the subway is very similar and recommended. Get up at a civilized hour, have a nice breakfast, and avoid the rush hour.

There are a number of Choice hotels in Paris. I tend to look for the Clarions, because they are usually a bit more upscale. Others have reported favorably on Quality/Comfort props in the city. If you have a particular arrondissment you prefer, check out the props there. Search (FlyerTalk) and Tripadvisor are your friends!

Good luck, and enjoy!

Edit to add: The sticky in this forum has links to reviews on a lot of Choice properties, including several for Paris.
