Great location - centrally located in Sevilla making almost everything walkable (Alcazar, Cathedral, etc).
The place itself is clean and comfortable. The double bathroom is also great if you have more people. It's located right next to a cafe that's great for breakfast in the morning as well as having some other good restaurants within a block.
Jose himself is a fantastic host - best airbnb host I've ever had. He has quick, clear, and useful communication and can help you out with a lot of things you might need or want to do during your stay. During check-in he goes through a rundown of the city pointing out the must-sees, great places to shop and eat, etc. He also has a few pages of info on all the sites for a little bit more information, times etc.
Apartment is also equipped with everything you'd need including everything you need for laundry.
