Loved the location. the Hotel is very well designed and comfortable

The room was very nice and hotel is super cute overall. It's super close to the heart of the Marais and very accessible to just about everything you'd want in this area. I would recommend it to anyone traveling to this part of Paris.

Great size room, stylish/quirky, very clean with great amenities and the perfect location within le marais

Hotel staff were super friendly & helpful.

The Hotel is very cool. The room was quite comfortable and large (for Paris). My only issue was the steps in the bathroom and lighting. It may just be too cool for me. But an enjoyable and comfortable stay.

Nice!

Great location. Interesting neighbourhood with loads of bar and restaurant options close by, and walkable to many of the key tourist areas. Staff were just excellent in every role. Hotel is a little quirky but fun and the room was really comfortable. Lighting in the room takes a bit of getting used to but this is only a minor point overall.

Great hotel, all the staff were friendly, helpful and nothing was too much trouble. Highly recommended.

Terrific spot in the heart of Le Marais. Rooms were wonderfully furnished and oversized compared to typical Parisian hotels. Great cocktails in the bar too.

Paying 800 euro + per night, I had expected service to be comparable to other 5 star boutique hotels. Reception was somewhat slow and there was no advice around a major event that would shut down easy road access to the hotel on the day of arrival. Chaos. No greeting at the door. One person working reception only. Hotel wasn’t particularly busy, but no room upgrade. Constantly bumping into cleaners in the hallways and lifts. Steam and Pool seemed to be frequently out of order. Service at the restaurant was poor. Even when not busy. All fine for a 3-4 star hotel, but this is not marketed as that - with pricing to match.

We will definitely return to stay again!

Fantastic, modern and cool hotel! Wonderful service in the hotel and bar and great location. Will definitely stay here again! Really loved Emily in the bar - incredibly helpful suggesting places to go. Super experience.

Great staff and amenities

Simplement incroyable. Localisation parfaite et espace décoré avec grand goût.

Excellent hotel.

Lovely hotel in a brilliant area. Rooms are very dark, especially the toilet and sink area, which I understand is mood lighting but it gets in the way of practicality. Very comfortable and stylish though.

Mice galore! Stayed on the first floor, which smells of chlorine from the very cold spa tub "pool" on the same floor. Saw two mice run through the corridor my first morning, makes sense for a hotel so newly renovated, and truly still working out its physical kinks (AC vents were not open in my room so it did not work, the sinks do not drain, phones are not all connected). Staff at the front desk mean well however the manager lacks empathy nor consideration for such a safety concern. The best part was at check out I was told they would refund one night of my stay, asked for confirmation - never heard from them again! Not surprisingly considering how unfazed they were by my room issues and my concern over mice. I have stayed at several Experimental hotels over the years, and in Paris every few months. So many better, cleaner stays near by and around. This opened too early and without consideration of quality and guest care.

Lovely stay. Executive rooms were huge and comfortable :)

Loved our stay at the Sinner Paris. This isn’t your typical chain hotel, definitely more of a vibe and for us it was a good one. The room was very spacious compared to what you would typically find in Paris. If you’re looking for a “traditional” Parisian hotel this isn’t it. We loved the neighborhood and the local food scene nearby. For reference, we left the Sinner to spend a few nights at the Park Hyatt Vendome which was twice the price however we enjoyed the Sinner much more!

We booked this last minute as the hotel we had booked was unacceptable. From the outside it is difficult to appreciate what awaits inside. Everything about Hotel Sinner was 10/10. I strongly recommend this hotel
