I had such an awesome stay at Silvia's studio. First of all my check-in was very seamless. Silvia was always quick to respond to my messages throughout my stay. She went the extra mile of giving me an overview of all the best things to see/eat in Seville since it was my first time. She also went above and beyond by doing my laundry for me and reserving a taxi for me when I had to depart early.
Location-wise, it's in a great spot right next to a lovely market. It's only a short walk from the city center and maybe a 20-25min walk from most of the sights you'll want to see. Very doable since Seville is so flat.
The space itself is exactly as advertised and decorated so nicely! Everything was clean and in order and Silvia even provided some light breakfast items for me to have. The shower was awesome and the bed was super comfy. The only thing was that the walls were thin so you could hear next door and also out on the street (the room is right at street level). I wasn't bothered by it much but if you're sensitive to noise be aware.
All in all I loved my stay and wished I could stay a little longer even! Would highly recommend to solo travelers like me or couples exploring Seville.
