Most importantly, the hotel was very clean. I would compare this whole hotel to a Premier Inn - cheap and cheerful (and not particularly spacious or luxurious, but then what do you expect?). Only one plug socket in the room, which was a bit annoying...
It is in Zone 5 of Paris so a travel card from zones 1-5 will get you everywhere and the station is only a 3-4 minute walk (it takes 15mins to get to the nearest big station in central Paris). Nothing much 'happening' in the area of the hotel, so you will need to travel elsewhere!
Staff were all really nice and friendly, not brilliant English but they did try and it was enough that we knew what to do. At the end of the day, you're visiting France, so why should they speak English. Not many of us speak French!
No restaurant in the evening available, and breakfast was very overpriced so I'd advise to go elsewhere or sneak your own bowl, spoon and cereal into your room!
Overall, it was good though and we had a great stay in Paris!
