We will be renting a car in Lund on a Friday afternoon, and returning it about 12 days later near Stockholm or in Stockholm.  We will be in the Odeshog/Vadstana area before Stockholm, and don't want to drive the car in Stockholm, so we are wondering what would be a city with a drop off, and also have a fairly easy bus or train ride into Stockholm.  It is a Hertz rental car.  The location we have to return it to now in Stockholm is 
  Location: CENTRAL RAILWAY STATION
  Address: MASTER SAMUELSGATAN 71
but we have never driven in Stockholm before.  We also do not use a smart phone.  Would it make sense to drop the car off in a smaller town, and which town would have easy driving and an easy to get to Hertz drop off?
Thanks
