Location location location! That’s almost all you need to know ;)
But the apartment itself, quite spacious, including all stuff you need for two ppl plus an extra room. Yes some kitchen stuff could improve but you are simply good to go with everything that is there. The apartment gets nice light in which is a delight during cold days, as we stayed there over March. As I also read in some other comments, the bathroom/shower is showing some age but let’s not forget that this is an old apartment in an old neighborhood. Speaking about the neighborhood, I honestly think the location is great. You have access to bakery, restaurants, cafes, etc. only if you walk for 2 mins. And they are all good. Hope this helps you decide :)
