Wow! What a beautiful place to stay. We recently stayed here for 8 days, no issues at all. Very clean neighborhood, with a G20 grocery store nearby. Chatalet Les Halles station and mall are 2-3 minutes walk. Very seamless check-in process with no real front desk personnel. Customer service via WhatsApp was amazing. Very close to the Louvre, Seine River, Notre Dame, etc. short uber ride to Eiffel and Champs-Élysées.
Good size bathroom with Hansgrohe top notch fixtures and water pressure is great. In our apartment, Toilet was separate from the bathroom which was nice. There are restaurants/cafe/bar in the bottom floor and can get very busy all days evenings due to happy hour. Elevator is sort of odd trapezoid shape and can fit a large travel bag and another person, but we had no issues at all.
Definitely recommend it to everyone.
Just hope they fix this three wheeled trolley in the apartment we stayed, which kept tipping over.
