If you've been to one of ibis budget hotel, it was exactly like that. :)
1. The room was cleaned daily, but the sheets were changed once a week, as far as I noticed. We also got daily clean towels.
2. The check in was quick and easy. The check out was even better, because there is an option to pay 5 euros to stay 2 hrs past the checkout time, or 10, for 4. This helped us a lot having the flight later in the evening.
3. We didn't try the breakfast, but there was a touch screen in the lobby with a few restaurants that deliver.
4. There were a few receptionists. Half of them spoke English, half of them didn't, but they were all very patient, so there were no issues.
5. The room was very well heated, with a private shower and a private bathroom.
6. As far as public transport goes, there are plenty of options within a few dozen meters after leaving the hotel grounds. The ride to the center is around 45 to 1hr 15 minutes, depending on which rides you take (t6, then m13, or, 379 then rer B, or, 190 then rer b). Bolt is also an option, and it will cost you around 25eur from the hotel door, to mostly anywhere in the city.
