Ea is absolutely the best host. She has been so helpful to me in getting around Sweden, understanding different cultural aspects and giving me random tidbits of information to help make me stay more enjoyable. Her place is near the train station and it is very convenient to get into the center of Stockholm from there. The public transit in and around Stockholm is 1st class so you won't have any trouble getting where you are going. I can't recommend her more highly for your stay!
