We stayed in This wonderful flat for two days in March. Belén is such a great host and welcomed us in quite a nice way, she also provided us with so many advices on what to see and where to eat/drink ! (She even parked her car in a street close by to allow us to park since we arrived by car so we wouldn't have to look for a place to park for free)
The flat itself is fully equipped and is close to about every main touristic places (10-15min walk).
If we ever come back to Sevilla I'll make sure to book this flat once more ! 5/5 fully recommend !
