Loved my stay at Hotel Dress Code! The location is excellent, close to Opera, tons of cafes/restaurants, shopping (Galleries Lafayette is just 2 blocks north), and a 6 minute walk to the metro station.
The included breakfast was also much better than expected and had a wide variety to choose from including cheese, salmon, fruit, eggs, bacon, pastries, and more.
The room itself was somewhat small (but that's to be expected in Paris) and very clean, stylish, and modern. I also loved that this is a smaller, boutique hotel, which meant not having to walk through a large lobby or down long halls. Everything was very convenient. There was always someone at the front desk, which was very helpful. I would definitely stay here again.
