Svolvær is in Lofoten.
There is an airport near the town.
There is an express boat service from Bodø everyday except Sunday. The journey takes about 3½ hours. There is also scheduled bus to/from Narvik (stops at Evenes Airport; no ferry on the new road). In addition, the coastal steamer Hurtigruten arrives at 7PM (southboud) and 9PM (northbound) daily.
Svolvær is really compact so the best thing you can do is walk.
There are many art galleries here.
See the WWII Museum with it's incredible collection of uniforms and its original chilling, Gestapo interrogation room.
It's not so easy to keep to the budget here. Narvesen kiosk is a good place to buy things such as drink. There's a bookshop in the town, art is being sold in many places and overpriced souvenirs are easy to find.
There's lots of different kinds of accommodation. Hotels are widespread, there's camping or you can get a rorbu (a traditional fisherman's cabin). Sleeping outside is possible as it is quiet, but the temperatures can be near freezing even in the summer and the cold wind from the sea doesn't help at all.
