I stayed here for 10 nights at the end of June with work associates and found the hotel to be beyond expectation.
For the price, I found it to be immaculately clean, the beds very comfortable, the rooms of good size and layout for Paris..... But the best feature of the hotel is the super friendly staff! They could not be more accommodating. Special mention to Samuel who was so kind and understanding to me after a difficult night when my bag was stolen.
Note: hold onto your bags ladies..even at beautiful restaurants!
The buffet breakfast was simple but lovely and the free snacks and drinks of an afternoon were a nice touch.
In summary I would absolutely stay at Hotel Joyce again.
