cdg hotel close to terminal 1

Budget? There's a Sheraton right at CDG; I stayed there some years ago and just walked out of the hotel doors and up to the departures hall. To get to terminal 1 from there, you might have to take the CDGVAL train, which should be pretty quick.

Last year I stayed at the Hyatt at CDG. It was a short shuttle ride to the airport in the morning.

I'd stay either of these places again, but I booked them with points. If I were paying, I'd hop on Booking.com and look for hotels close to CDG, within my budget, and read the reviews (people usually mention the hotel shuttle, how quick it is, etc. in reviews of airport hotels).

There are also an Ibis and a Novotel. I've stayed in the Novotel twice and it is fine. Both are Accor Hotels with eh Ibis being on the budget end. When you book, be sure you are booing at the hotel AT the CDG Terminal as there are several in the area.

There are a number of hotels at Roissypôle which is located between Terminals 1 and 2, with Terminal 3 being a short distance away, and connected with the free rail line called CDGVAL. The RER B from Paris first stops at Roissypôle before continuing on to Terminal 2.

Hotels located at Roissypôle are the Ibis and Novotel.

Hotels on the CDGVAL line:
Citizen M
Hilton
Pullman
Ibis Styles
Mercure
Holiday Inn

The Sheraton hotel is in Terminal 2.

Your closest hotel to T1 is the more expensive Sheraton inside T2. Next is the group of hotels next to T3, including the Ibis. The post above this one lists the hotels. This area is where we always stay. These hotels are reached by internal shuttle train.
Finally, the off-site hotels scattered around offer shuttle buses that take you to T3 where you get off and board the internal shuttle train. We never stay in these areas anymore after a couple of experiences with late shuttles and full shuttles passing us by.
