Really nice and comfortable apartment with everything your need, less than 2 km to centre of Stockholm. We walked from there through the entire city.
My family (5 adults) travelled by car: Stockholm parking zone 3 applies (max 24 hr for non-residents, accepts bankcards). Note: at some places (e.g. Skansen) only creditcard is accepted. Alternative is a parking account with app/SMS-features can be used (to be created upfront).
Very friendly host, explained all well, enjoy his home and this beautifull city.
