We stayed here for about 2 weeks. It's in a great location, walking distance to everything. The wifi is super fast and stable, which is important for us since we work remotely. The place was clean and the hosts were very responsive.
The only downside is that the bathroom smells a bit like sewer. We used an air freshener and kept the bathroom door closed to minimize the smell.
We would recommend this place to others looking for a place to stay in the heart of Seville!
