The bedroom is on the ground floor facing the street, with many cars passing by as it is a major road. You cannot open the windows because of the noise of the cars. You also can't open the curtains because people walking by can look into the room (basically right on to your bed).
To their credit, they had air conditioning, but this was the only way to ventilate the room (which got very hot whenever it was turned off, even though it wasn't really hot out). They also had a double window so that you could not hear the cars outside when the windows were closed. On the plus side, it is clean and the bed is comfortable. It is also conveniently located near the main train station and about 15 minute walk from the beginning of the city centre.
But overall, I was expecting better, and if I knew this information in advance I would not have booked the place.
