About 15 minutes on foot to the cathedral and La Giralda, plenty of restaurants around. The room was clean and it was nice to have a private bathroom. Thoughtful amenities such as snacks, coffee, tea and a small electric kettle provided.
Do note the room can be stuffy and dim due to the lack of natural light, even with the door to the small balcony open. Although there seems to be air-conditioning, I didn't seem to see access to a remote. The bed and pillow were hard and uncomfortable. Homely decor, reminiscent of a child's old bedroom, with boxes in a corner and an old exercise bike. I personally found the clay bust of a woman next to the bed unsettling.
Communication could have been more effective; when I arrived, I had to wait along the street for some time until another guest opened the door and let me in, as there were no instructions about how to get in and texts and calls to the host were unanswered. The host was nice when I met her. Additional toilet paper was provided on request, and she kindly helped me to arrange an early taxi to the airport.
Overall, worth a stay if you want to be reasonably close to attractions, won't be in the room much, and would like a private bathroom. However, I would seek other accommodations if I return to Seville.
