My parents and I had a wonderful stay at Rocios. You will not be disappointed. We got in late and Reyes, a wonderful woman let us in and explained everything. She was very welcoming.
The airport is about 25 euros to her apartment and the train station is about $8 euros.
The apartment is located walking distance to everything. There's even a market just around the corner if you want to get fresh fruit, veggies etc.
Bars/tapas are all near her home...walking distance.
I enjoyed my stay and if I ever return to Seville I will look her up again to reserve the room.
Thank again Rocio!
