We travel a lot, and we were worried about the hotels in paris in general. But this hotel was the best decision in Paris. We would never stay elsewhere than at hotel belleval. There was a warm and friendly welcome everyday we entered the lobby, and all of the staff did everything to make us feel at home.
We loved the room, we slept very well, we relaxed in our bathroom and in the sauna; and anytime we returned to the hotel after hours of exploring paris, we felt like coming home. Exceptional design, exceptional warm-hearted service, good restaurant. Familiar atmosphere. New hotel, cosy courtyard with tables outside and heating lamps, cosy room, best quality bed; enough space (we had the deluxe superior room).
Be aware there is no wardrobe - we took the clothes from the suitcase. But this was the only disadvantage, not a big problem in our 6 days stay.
