Maribel's place is really well located, right in the center of Sevilla and within walking distance to most attractions. The place was clean, well decorated, and very functional.
The host was friendly and kindly took the time to show me a bunch of recommendations of places to visit upon my arrival. Overall a good place if you're travelling by yourself and don't need a lot of space since the room is fairly small. It worked fine for my needs, but something to consider if you're carrying a lot of stuff, for example.
