This is a very comfortable two room, 3rd floor apartment in a very lively neighborhood, across from the main entrance to Skansen and tucked behind Stockholm's amusement park on Djurgarden. There's a big sunny living room, a small kitchenette on one side of the bedroom, a nice clean bathroom with shower. There's an elevator and free washing downstairs -- you have to sign up but it's easy to do. The small patio is a great place to sit and drink your coffee and watch people go up and down on the higher rides at the amusement park.
The only reason this doesn't get 5 stars from me is that in the summer there is loud music from Skansen (an open air park and music venue). On Tuesdays it starts in the morning with rehearsals that culminate in the evening with a live sing along show (apparently televised). On Thurs/Fri/Sat there are Swedish pop bands playing at night. They all ended around 11 when we were there.
That said, it's super convenient to every attraction (incl the amusement park and Skansen). The #7 trolley is lots of fun to ride and will take you downtown in a jiffy. The 80 and 82 ferries are very close, run all day and are fun way to get around. There are lots of great walks going away from the town into Rosendal Park.
