I booked this hotel without hesitation after reading the glowing reviews on tripadvisor... Only to feel rather disappointed on arrival.
I transferred to this hotel from Holiday Inn Clichy where my group tour ended. We arrived before check-in time and was flatly told by Ludivine we had to wait till 3pm. Waiting was fine, I was more appalled by the blunt and not too welcoming stance we were greeted with.
Perhaps this was the not too hospitable service typical in Paris I thought. Or perhaps cos we were Asian, as I saw her greeting other check-in customers warmly even showing them to the lift later on.
On the room, it was tiny, which we accept since we only paid 143 euros/nite. But the shower leaked large qty of water to rest of the toilet every nite! Find this unacceptable as we have to mop with floor mat constantly I believe the shower door silicone strip had been too worn. To minimize leaking we have to stand sideways and slant the shower head sideways. The basin tap hot and cold shower was funny, tap indicated cold water but give hot water and vice versa.
We also had some inaccurate instructions on which metro stop to alight to collect lourve tickets. Also on how to connect from metro to RER to Versailles.
The good points - next to Galaries Lafayette and Printemps. Many metro lines available. Near to several Chinese food stalls, cages etc. One of the male staff offered us discounted Disney tickets which we are grateful for his helpfulness.

I come here with my husband and stay here for 8 nights, choosing "comfort room" type. It is really a quite street, I think when I choose this hotel. Apart from the first night for sleeping well, my husband and I were awake at 6:30 am every morning, because the shop next to the hotel down-loading the goods regularly except weekend on Sunday. If you could not sleep well at night, you can absolutely hear the toilet flushing from other tenants too, in particularly at 12am. See why I mark "poor" in sleep quality.

We stayed at the hotel for 4 nights in October. It was located in an extremely convenient location ie. Printemps, Lafayette, loads of other shopping places, the Metro, restaurants, bakeries, walking distance to the Opera, Place de la Concorde, Champs Elysees, Fauchon and of course, Laduree! We booked this directly with the hotel itself and communicated several times with their staff namely Jose, who was very efficient and addressed our concerns most professionally. Their other staff, a blonde hair lady, was very helpful when I needed assistance to print my boarding pass and even a Lafayette discount voucher! The room we had was a very basic room, very tiny with just a double bed, a small rectangular table, a plastic chair with backing, a tiny cupboard and a shower cubicle with attached water closet. We did not have their breakfast as for Euro 13 per person, we could have breakfast for 2 on our own. Coffee and tea making facilities were not provided.
Overall, the room (Room 305) we had faced an internal courtyard and was clean and tidy, the bathroom was okay with sufficient shower gel and shampoo provided. We did not have problems with noise but the lift was just big enough for 2 persons or 1 person with 1 big luggage. Teeny weeny lift indeed!

My wife and I stayed at the Hotel Opera d'Antin for 3 nights in October. The location was superb, with a choice of restaurants for all budgets nearby. We were fortunate to have a breakfast included package. Our room was a 'Comfort' room, the mid range that the hotel offers. The room & bathroom were clean and comfortable, although small. The sound proofing was very efective, with little noise from the street outside.
We found the staff helpful, our only negative was that we were provided with one pillow in a double room, when we requested more we were only given one as we were told that 3 extra pillows were "too many".
A good hotel for a short break in Paris!
