We stayed at Giovanna's apartment for three nights & it was lovely. Not surprisingly, it has that delightful Swedish feel & is spotlessly clean. She had fresh fruit, biscuits (cookies), coffee & tea to get us off to a good start in the morning.
The Kartorp (chartorp is close to the pronunciation I think) Metro station is a 7 minute walk. There are two grocery stores near the station, & a restaurant/bar with a neighborhood feel called Kartorp Grogg. We also enjoyed a delightful coffee shop/ restaurant which is close to the Slussen metro stop called Lisa's Cafe.
