Lovely stay at Scandic Alvik, we stayed four nights in order to attend the Taylor Swift concert. Intially I was worried that it was located outside the main part Stockholm, but there is extremely well functioning public transportation basically at the front door taking one there in 15 minutes.
Hotel itself was quite modern, room we stayed in was freshly renovated and clean the bathroom especially was great, beds were squeeky but comfortable enough, super friendly staff, very nice breakfast all for a very affordable price.
