I've been reading the forums for awhile now but this is my first post.
This is the first trip to Europe for my wife and I. We've booked a Best of Europe in 14 Days for next June. The tour starts on a Monday and we plan to arrive in Paris the preceding Friday morning so we need a hotel for three nights. The tour hotel, B Montmartre, is in the south east corner of the 17th, almost in the 18th really. The neighborhood seems nice based on reading some tour trip reports and I'm guessing that staying there would be simpler in terms of handling luggage and costs. On the other hand it also seems very far away from most of the things that we'll want to see.
In reading many of the posts here I see recommendations for first-time visitors to say much closer to the river in the 4th or 5th. I've also seen some recommendations about staying in the 7th. This makes more sense to me because we would be able to walk to more sights but perhaps I'm making too much out of needing to hop on the metro to get downtown first. I'm interested in hearing what others did on their first trip.
