Elena's apartment was lovely and made us feel right at home in Seville!
We were welcomed by her friend who let us into the flat and gave us some recommendations for the nearest super markets and a great little tapas bar close by, where we ate several times during our stay.
I cannot stress enough how well the flat is located! There are quite a few little artisan shops around and a lovely small-scale market hall within easy walking distance (5-10 minutes). You can reach the city center with its main attractions (the cathedral and alcazar) within 20 to 30 minutes by foot and we even walked all the way to Placa de Espana in maybe around 45 minutes.
The flat as such was great as well; very nicely cleaned with a lot of attention to detail and well prepped for our arrival (with some cold drinks in the fridge and a pack of traditional biscuits). The place cools down easily with well working aircons; bed and couch are both very comfortable; and the kitchen really has everything you might need or want (including a sushi rolling mat!)
We cannot but recommend Elena's place for a stay in Seville and would always come back!
