The flat is fantastic in a lovely neighbourhood! Very close to everything, basically. I love Södermalm. Kitchen has pretty much everything one needs on a short trip.
For all continentals out there: breakfast in Sweden is porridge and coffee ;) And the bed is rather on the soft side, which isn't bad as such, but there might be people out there who need to know. Ella was very communicative beforehand and told me everything I wanted to know (supermarkets, fav coffeeplace).
