I had a great stay at Hotel Etoile Trocadero. The check-in and check-out were very easy, the staff was incredibly helpful, and overall interaction with them was always nice. Almost all of them speak English, so you can default to that if your French is not too strong. My room was always clean, and everything worked just fine. I didn't use the AC, but it was there in case I needed it. The breakfast was great, with many options, and fresh, good coffee too. I'd definitely come back.
