My partner and I stayed 3 nights in a double room with shower and balcony.
Check-in was friendly and efficient. The staff were very courteous and helpful during our entire stay.
The room was clean and a good size, the bathroom/shower was smallish but by no means cramped and the bed was comfortable. We had a cute little balcony just big enough to fit two small chairs and a small table. We had no issues with noise in the hotel or on the street.
There is a lift for those that struggle with stairs however you do need to go up 1 flight of stairs to get to it. They are steepish however we had no worries using them (we were up about 4 flights of stairs). I cannot comment on the breakfast as we didn't eat at the hotel.
The location was perfect for us as we enjoy walking. We walked from the hotel to Arc de Triomphe, Champs-Elysees, The Eiffel Tower, The Louvre and Notre Dame and didn't find it any trouble at all. However, there are also 2 metro stops close to the hotel.
All in all, a fantastic hotel with helpful and friendly staff. I wouldn't hesitate to stay here again or recommend it to friends.
