Slow Travel and do not forget the forum. You will find plenty from people living in Paris giving advice.
My last trip to Paris was over three years ago and it was my third trip. I could not give you a place to stay because frankly I do not know what they are like today.
My Advice is Paris is expensive, very expensive. To offset the cost I bought Paris Museum Pass. It was good for five days access to 70 museums. Best of all I did not have to wait in line, show the pass at the entrance, I am in. I could go back to the same museum as many times as I wished for the five days. I could go to the Louve and Orsay everyday I was in Paris and not wait in line or have to pay to enter.
Paris has a good subway system and you will need it to get to the sights, because they are all spread out. You will need a good Paris subway map. The one the Paris tourist office give out which was free, was way to small to read. There is a subway pass.
This is not to say not to walk in Paris and take the subway. Paris is a great walking city and has bridges that are works of art themselves. The only way to see this is to walk of the bridges and that goes for the streets too.
For a guide book pickup I recommend the Eyewitness Top 10 Paris guidebook from DK. It is small. Lists out all the important places a first time visitor to Paris should see. Has maps and even a good subway map.
Check with the Tourist Office about the Versailles if you go. They have the huge garden in the back that stretches the horizon where the sky meets the ground. The garden has these amazing looking statues. But if you go to Versailles make sure it is when the water fountains are actually working. It is mind blowing to see and the Tourist Office should tell you when or may someone on Slow Trav.
The Eiffel Tower has to be done twice. Once in the day and then again a night. Same steel tower but completely different experience. I have visited 10 times already.
Visit Montmartre on the weekend with a the street painters are working the tourists. Make sure you walk up and down the stairs, if you go you will know what I mean.
I think the best night time view has to be from Montparnasse. The building is not much to look at, but from the top it has the best night time views that is because the Eiffel Tower is in it.
Have fun. I certainly did when I was in Paris and lucky to done it three times.
