0.44km from La Penderie RestaurantWe stayed at CasaO last weekend in the Vivienne room and enjoyed our stay. The room is modern and clean, with hardwood floors and a shower with excellent water pressure. The bed was comfortable and although the window was large and looked onto a main street, it was not loud. The air conditioning worked well too. This hotel is well-located, within walking distance to Les Halles, St Germain, the Louvre, Le Marais and Ile de la Cite - we walked everywhere. The check-in process was straightforward and convenient, although you need to ensure that you receive your digital access code prior to arrival. The breakfast was very good, with coffee, tea, croissants & other pastries, breads, ham, cheese and yogurt. Virginie took great care of us, and when we mentioned a gluten intolerance, she immediately went to obtain gluten-free bread which was very much appreciated. We were also able to leave our luggage in the hotel after check-out and returned in the mid-afternoon to retrieve it. We liked the boutique nature of this hotel, the location and the cleanliness. There isn't a manned check-in desk all the time, but that didn't bother us in the slightest. This hotel provided us with an excellent base for our time in Paris.
