Great location that is maximum 30-minutes walking distance from any major attraction in Seville Centre. The apartment is decorated nicely and was fairly clean. Check-in and check-out were seamless, and it was great to be able to leave my luggage at the sister property for the day while I waited for check-in time and explored the city.
Downsides were that I had a basement apartment, which was a little bit hard to control the temperature of, and the bathroom smelled slightly. It was also extremely noisy at basically all times of day and night, but that didn't bother me--if you would find it difficult to sleep through, it's something to keep in mind.
