Stayed here 3 nights in November with family in two rooms. My room was certainly bijoux but it never felt claustrophobic in the least, thanks to a high ceiling and very clever design.

Beautifully executed interior design - Considering the room rate, it's nice to see what you're paying for! My favourite was the curtains in my room (but never tempted to "do a Maria" on them, honest!), and my goodness I wanted to pack the whole amazing bathroom and take it home with me! Everything clean and super well-maintained.

Breakfast quality was very decent with great service by the kind and observant crew. In fact I found the service across the board everywhere in the hotel quite brilliant.

Any niggles? Lack of room-service per-se (it's an order-out service, seems pretty much tied in with restaurant opening hours but don't know for sure); no tea/coffee facilities in the room; the lobby bar closes quite early rather than the more traditional "open until the last guest retires" arrangement - I don't know what the management might think about an honour bar, though it being on the ground floor facing the street might not make it such a great idea....

I've been for 3 nights at this hotel for business.
The hotel is modern and nice. The decor is unique, made ​​of different fabrics, patterns and colors.
The room was well-kept and nicely decorated, but I found it excessive. The room and bathroom were clean, but the towels were ruined.
Good location.

I absolutely loved Hotel Keppler. This is the quintessential "boutique hotel." I think there are about 39 rooms, and the lobby area is small, yet quaint, as are the actual rooms. But I didn't mind the size of the rooms at all. The space in the rooms are used so efficiently that the rooms seem 3 times as large. The customer service at the Hotel Keppler is top-notch. All the staff was so gracious and helpful. The location is near major Paris avenues, such as Marceau and Champs Elysees. The next time I return to Paris I WILL stay at the Hotel Keppler.

I have stayed at the Keppler for 3 nights in November 2012. Having read the reviews on trip advisor, I decided it should be a good choice. But I was pleasantly surprised by the professionalism of the staff and the quality of the rooms. Everything is 5 star ! I presume the only reason it is a 4 star hotel is because they do not have a swimming pool and a restaurant. But apart from that every detail is taken in consideration, and the staff treats you like in most 5 star hotels. We booked a standard room and were upgraded to a executive room. The room was beautiful and large for parisian standards. We loved our stay there, will go back next time i'm in Paris.
