Our stay at this beautifully decorated apartment was great! It is not in the city center but everything is walkable and the tramway connection is perfect. The national gallery is very close and the surrounding area is very pretty: lots of cafés, small shops and places to go eat. Marius had great recommendations for a nearby breakfast spot and the kitchen was equipped to cook (we only made coffee, but if your budget is tight that is a great thing). The toilet is across the hall and not in the flat but private, so we weren't bothered by that. You can really feel the artistic vibe in the whole building and it's really cosy just to stay in as well!
The only thing I would see as a downside is, that the tramway is so close that you can hear it quite loud in the flat. We got used to it quickly, but if you are sensitive to that kind of rattling sound that is a good thing to know and maybe to pack some earplugs :)
All in all we felt very welcome and were happy with everything!
