Me and my partner stayed at the apartment for over a week.
The place itself is super nice as described, except the double bed is actually two single beds which was really uncomfortable for a couple to sleep in, and the water boiler is kinda small so we often ran out of hot water.
Now about the location, I was surprised that nobody had mentioned this in the other reviews, but the area feels unsafe and unpleasant. if you go up towards the castle it's all nice but if you go down to the city you need to go through an area filled with drug addicts and dealers. We often felt uneasy and usafe walking there.
Just want to mention that the apartment itself felt totally safe, I am referring to the neighborhood itself.
