The apartment is lovely, tucked away in a building at the top of some stars right near a metro station. There are views out of the two front windows of the castle, which was just beautiful (2 seats at the windows for a coffee in the morning - bliss!)
Apartment is a very good size for 2 people, a well equipped kitchen, very comfy bed and nice shower. All of the extras you could need (hairdryer, towels, iron etc) which was a massive help as we just travelled with hand luggage.
Location is great too, easy to walk around from there but as I say, close to metro and tram stops if you wanted those methods too.
