My wife and I stayed at Au Pacific Hotel for 5 nights and we had a great time there.
It's a little hotel but is the rooms are quite nice, clean and location is superb(close to Dupleix - line 6 - and Avenue Emile Zola - line 10). People at the front desk is very helpful and all of them speaks English. We got stuck in Paris due to a strike in Belgium and they could arrange us a room for an extra night. If you happen to be there on a sunday, don't miss the amazing street market under line 6 subway. Nice place and I'm sure when I come back to Paris, will book it again.

We booked this online because it was one of the cheapest hotels (73 euro/night) we could find in the central area that also had some good reviews. Pleasantly suprised by what we got for the money - super clean (if a little shabby) rooms, pleasant staff, easily accessible to the Metro, and a great neighborhood with an excellent selection of food and drink options for the budget traveller: Boulangeries (B. Maeder Boulangerie Alsacienne on Rue de Lourmel), superettes, takeaway joints (7 euro hand-stretched pizza at the Greek joint on the Boulevard de Grenelle), and bars ( 5 euro happy hour special at Le Zinc on Avenue Motte Picquet; large beer selection and tasty food at Le Dernier Metro on Boulevard de Grenelles). Would definitely stay here again.

This hotel is great for the price. The turndown service was completed everyday with fresh towels, cups, shampoo and soap. There is free wireless internet that you simply get a username and password from the front desk to use. The front desk service was always friendly. During our second day there, our other travel plans were cancelled so we decided to stay there another three night. The hotel accommodated us without trouble and even gave us the promotion price were paying for our original booked nights. (I should add that the hotel was fully booked the whole time we were there)
We did not eat the breakfast provided there but we did have their coffee in the morning which is less expensive than getting out in the city. It was not bad at all.
The hotel building itself is old, like many buildings in Paris, but it is kept up to a decent standard. The room we stayed in was very comfortable, the in-room bathroom was a decent size with fully functioning facilities.
The location of the hotel was perfect for what we wanted to do, which was explore Paris by foot and public transportation. It is a short walk to the Eiffel Tower, subway and train stations, and has many inexpensive cafes scattered around it.
In other reviews I have read that the rooms are small. I think that all depends to what you are used to. For European standards the rooms are average sized.

this was a great hotel the first time we stayed i couldnt believe how close it was to the tower i first booked it over the net and o boy how great was it we have had 3 family members stay there on our recommendation
its clean the showers are great .nice and hot.
breakfast was nice plenty of it continental type
the only thing that wasn't there was any English speaking shows on the TVs
wait till you see the size of the lift its fun
over all a great hotel i would really recommend it as you can see i have rated it very high it really is that good
