Any comments about the Ibis Hotel near to CDG airport?
It has been a few years but I found the rooms very small. I have stayed in a few other Ibis hotels and they had much larger rooms.
Be aware that there is more than one Ibis branded hotel at CDG. Look at the Accor website to see the different options and then see reviews for each one, as they could be quite different.
We stayed at the Roissy Ibis a few years ago, and it was fine. The room was small, but not much smaller (if any) than the one in our Rue Cler hotel. The breakfast was skimpy, but everything else was fine. The hotel was very clean, the staff was helpful, and the shuttlebus a real convenience.
I stayed at an Ibis hotel at CDG back in 2017; my last night in France and I had an early flight out in the morning. Bretty basic accommodations, it was clean and well-run, but nothing to write home about. I noticed they got a lot of pax being put up overnight by the airlines due to missed connections. (Kinda a clue when there is a long line at the check-in desk, all weary-looking travellers.)
There was a buffet for dinner and breakfast (and presumably lunch). Adequate food.
The food situation at some CDG hotels is not good. The place I stayed (possibly the Ibis you're considering, because I'm all for cheap hotels) didn't begin dinner service until 7 PM, an inconvenience for travelers with early wake-up times the next morning. If I end up in that situation again, I'll try to pick up a good salad or sandwich before heading out to the airport.
We stayed at the Melia hotel https://www.melia.com/en last month which is down the street from Ibis. Rooms very basic but clean. Small restaurant which was adequate.
We stayed at the IBIS Styles hotel at CDG last fall. Very convenient getting back and forth to the airport on the CDGVAL. Busy hotel, room was basic airport hotel and perfectly adequate, restaurant was fine for dinner and breakfast.
As has been said there is more than one Ibis in the area. We have always stayed at the Ibis Paris CDG Airport when flying out of Paris. The rooms are small, plain and spotless. We have found the breakfast buffet to be very good. If you take your time, it's about a one minute walk to get to the RER station and the free shuttle to Terminal 2E or the RER if you want to go into Paris, We will be back in Sept.
We spent a night at the airport Ibis (not Roissy) and it was fine. As others have described, clean and comfortable but nothing fancy. Very convenient to the terminal. I'd stay there again if I had a morning flight. There are several other choices as well. I'd suggest staying at the airport rather than the town of Roissy so you don't have to rely on hotel shuttles.
