I highly recommend staying at Barbara’s apartment. It’s very clean and has a lot of what you need for a comfortable stay in Seville. I did not meet Barbara but I felt like I did because she was very communicative. I had a lot of questions for her and she answered all of them timely. She also had a lot of good local recommendations for restaurants, what to order, and what to do. The apartment is a 15-minute walk from Santa Justa train station, 15-minute walk to the Cathedral and Royal Alcazar, and 10-minute walk to Las Setas. There are lots of restaurants around and grocery stores.
