This was my home station during my time in Stockholm and the 8-bit game design tiles made riding the metro a little more pleasant. The MTR had staff pressure washing the station so that it stays clean. It's an outdoor station so it get's super cold and hot depending on the season.
In general I love the art of the Stockholm subway stations and this one is one of my favorites since it's a bit different. The kids think it's fun.
If you're looking for art around the city, this place has got some fun PAC-man tiles to look at!
