It's an amazing historical building in a very central location that can reach many historical and tourist locations by walking, Metro, train or bike.
The building exterior makes for a great picturesque backdrop that matches the nearby City Hall.
The room itself is rather small, bathroom sliding doors are glass that don't offer privacy and the sink was extra small. Breakfast was good. Overall, it is overpriced for the amenities but you'd be paying for location and historical value.
