Stayed in the ATN hotel with a friend and we both enjoyed our stay here. Hotel has been recently done up so is nice and modern inside. It's located on a quiet little street but with cafés and restaurants within walking distance.
Rooms are small but comfortable and clean. Only fault is that there was no safe in the room. Bathroom is small also but has new and modern fittings and had a fab power shower !!! We had breakfast included. It was a cold buffet and you could help yourself to as much as you wanted.
We dealt with a few different staff members at reception and all were lovely to deal with, very friendly and helpful with information. We used the metro alot and there was a metro station just down the road, very handy for getting around. Hotel was within walking distance of the Opera and the louvre museum too.
I would have no problem staying here again if i was going to Paris
