This location is located right next to everything you'll want to see in Porto. Being walking distance from everything is fantastic. The amenities / renovations are very modern and very sharp; the high ceilings are a treat as well.
One thing to note is that the unit doesn't have AC. We were in Porto during a heatwave and the unit felt a bit warm until we figured out how to open the upper-level windows to let in some airflow. With some airflow and the provided humidifier and fan, the temperature felt great.
