Hotel help in Paris.

How far are you willing to walk before or after a walking tour or self-guided walk? I am asking because if you stay in hotel with a short walk to the Historic Paris Walk, you will automatically be quite a long walk away from the Champs-Elysées walk and Place du Trocadero. I feel like that at some point you will have to take mass transit or a taxi to get to someplace in your schedule.

In order to be as centrally located as possible, consider stay on Ile St. Louis. We've stayed at the Hotel des Deux-Iles, and there are a couple of other hotels on the same street, and one of them is a sister hotel. Cross the river one way and you will be in the Marais -- cross it the other way and you'll be in The Latin Quarter. Walk to the end of the island, cross the bridge, and you'll be at the back of Notre Dame which is still being reconstructed. The Metro is nearby and getting anywhere is not a problem. There are several restaurants on the island. If you stay there, we can steer you to a great little place for breakfast as hotel breakfasts seem to be over priced for what one gets. We can also tell you about several places for lunch and / or dinner on the island as well.

Where would be a location where we might only need to take the subway once or twice? We don't mind walking a mile or two to the site. Thanks

With the exception of Place du Trocadero and the Eiffel Tower, most of your itinerary includes sites concentrated around Ile de la Cite, where Notre Dame is located. That is right next to the Latin Quarter. So, barring finding a hotel on Ile de la Cite, the Latin Quarter is where I would look. Plan on taking transit to the Eiffel Tower/Place du Trocadero.
And book your accommodations ASAP— prices even in June are sharply rising with each passing day.

Going in June, to Paris in Olympic fever season! Do you have a hotel? That might answer your "walking" vs Metro/bus concern.

janet_kupfer raises a good point. I think that you you are looking for hotel suggestions based on your headline but I have no idea what your budget is. In any event Hotel de la Rue de Lille might work for you. It's a short walk to the Musee d'Orsay stop on the RER C which you take to the Champs de Mars-La Tour Eiffel and cross the river to Place du Trocadero. It's about a 15-minute walk to Tuileries Garden. Good luck.

...where we might only need to take the subway once or twice? We don't mind walking a mile or two...

While there is a lot to be said for walking and absorbing the atmosphere of Paris, your time there is limited. In order to make the most of the time you do have, you might want to consider taking the Metro to your desired location and then doing a short walk about if you like. The Metro works, is easy to use, and you can go almost anywhere. Believe me, trying to walk from the Eiffel Tower back to Ile de la Cite is brutal and time consuming.

I agree with all the comments already. I love that you want to experience the walkabout in Paris. 2 days to see anything in Paris is a challenge. To maximize, your stay I'd say hire a guide. If you're not planning to go into any of the destinations you listed, then it's doable. However, it's likely you'll be curious about what you see and want to go inside. Reservations for every site is essential. In fact, I don't know if you can get into anything these days without one. Lines will be long if you don't have a reservation for sure, and likely long with one. The metro is a great tool as you'll have plenty of walking even with the metro. The Louvre will take up most of your time while visiting. Like someone said, the olympics will be in Paris, so there will be a lot of construction possibly which may affect anything you do. The actual games start 7/26. I encourage you to get a place now, because you might actually be too late. I hope you get lucky.

The other thing you don't mention is your budget for lodging. I'd be prepared for sticker shock. The prices for 2024, with the Olympics in town, is eyewatering. And that's IF you can find a place. I wouldn't dawdle.

Grab the Rick Steve guide and focus on staying in the Marais area. We stayed at The hotel Beaubourg nice, small but centrally located plus near several metro stops. One that stops at Louvre. Metro is easy to navigate and reasonably priced. Paris is very easy city to get around if you use the metro

Morning: Follow my guidebook's self-

Arc de Triomphe down the grand
Avenue des Champs-Elysées to the
Tuileries Garden,"

This is completely NOT in your question, I realize, but to me walking down the Champs-Elysees is kind of boring. To me, again, there are many more places that are more interesting and where you might get a different feel for Paris other than a string of chain stores.

Yes, to the Tuileries or perhaps another of the big garden areas. Maybe a market street, of which there are many, or one of the neighborhoods. I'd go with a Paris Walks walk. They are inexpensive but a walk with a guide will give you magnitudes of understanding the history and culture of Paris. (www.paris-walks.com) . They have many themed walks if something is of particular interest to you! You don't need to go to museums or churches although there are many.
