Walk around, enjoy the beach, the jettys, have a barbeque. You can walk along the water from Hornstull all the way to Skanstull. Takes about 40 min.
A nice park to stroll around and enjoy all the "koloniträdgårdar" (small garden spots to rent) with they're mini-villas. In the summer there's even a small beach. There are also mini golf, boule and a sauna. Continue the walk along Årstaviken and stop for a coffea, drink or food somewhere along…
Go for a swim in Tanto, Tantobadet. 10 minutes walk straight south on Södermalmsallén, turn right down by the water. Crowded yes, but hey, this is a perfect chance to meet locals. Off hours is of course nice, a morning swim?
Great park that has everything from an "artificial beach" to an outside gym and a lot of grass area to relax.
“Nice to stay here if you want to swim in Mälaren and come close to the nature. A cosy small harbour with lots of nice, small boats to look at”
“This place is three floors and every floor is it’s own ’type of place’. In summers there is also a rooftop bar ! Bottom floor at the moment is a bar/Cevicheria. Good food and not too expensive. In weekends it turns in to a club in the later hours :) Middle floor is bar Laika - more of a bar/hangout place. There is a double bed you can hang out in. They serve simpler bar food like fried chicken and sweet potato fries. Top floor is italian pizza-place (and pasta) called Enzo’s. They usually also show football/soccer on the televisions so it’s sort of a sport-bar type restaurant. ”
“Nice café. Perfect for breakfast and then a nice 30 walk into Old Town along the water by Södermälarstrand, the street Hornsgatan or the nature and water by Årstaviken. ”
“This little cinema (BIO RIO) in Hornstull (40 min walk or 2 stops away with the tube) is my favourite cinema in the city. They will show the independent movies as well as the blockbusters. The cinema is old and very beautiful, if you want you can eat your dinner and drink a glass of wine while watching the movie (this you have to pre book). This place is perfect to come to for a drink while watching the sunset over the water, before you watch your movie (or just come for the drink, the dinner you should eat somewhere else though).”
