Perfect situation in Gamla Stan, access very easy and indications from host very clear.
Living room big enough for 6 people without being all « tight » together.
The flat is very quiet with all windows open despite its very central situation.
It also keeps cool under the very warm weather despite its situation under the roof.
One additional sofa or a bigger one and a few small equipment such as cissors would make it 100% perfect.
Definitely a great place to visit Stockholm !
