This is a great apartment, much lighter than most and very stylish and comfortable. There are very large building projects on both sides of the apartment but then this common in Porto. It did mean we were unable to open Windows or use balconies during the day due to noise. That said the double glazing blocks the noise very well and the aircon is very good.
In the evening you still have an uninterrupted view of the adjacent palace. I would stay again.
Communication is excellent and check in easy as there is a door code.
