The location is great with easy access to both the old and new towns. However, because of this, the street outside the apartment can be noisy late into the night, although it's mostly people walking by as there are no pubs or restaurants directly downstairs (which is a blessing).
The room is quite small, which is fine for those who just want to have a comfy bed to sleep in. The bathroom door is made of glass, which means using the bathroom will light up the whole room. If you are travelling with someone and are sensitive to light during your sleep, this might cause some trouble for you.
The soundproofing between different rooms in the apartment isn't that good. We were lucky that when we stayed there, there were barely any other guests. However, every time the other guest or cleaner went in and out of the room and talked in the hallway (defiantly just at normal volume), we could hear their footsteps and voices clearly in the room.
It's overall pretty good value for money.
