A very convenient train station. We lived near the train station, in Radisson. A minute's walk and you find yourself in a dungeon city. There are many different shops, cafes, a metro station and most importantly a railway station from which you can reach Arlanda airport in 18 minutes (Stockholm-Arlanda express 379 kronor for two, bought tickets in the middle of the station at the information desk). There are also regular trains to the airport. I really liked the train station.
An excellent train station, combined with both the bus station and the metro, and is located in the city center and any transport is available. The station is equipped with everything necessary from car storage rooms and cafes, to shops and hairdressers. There are elevators, escalators and smooth surfaces everywhere, no need to carry suitcases on yourself. Anyone who has used the Moscow and St. Petersburg railway stations and the metro will understand me.
Fuss. Always. Not very clear designations. They are interrupted in critical places. The most difficult thing is to get to the right metro line without confusing it with the lines of local trains. Or come to the surface in the right place (shopping center, bus station, etc.). Fortunately, there are many assistants in yellow vests with the designation "i". They will always answer in English. So try to pronounce the destination clearly.
