We stayed a week in early November, and everything was exceptionally good. The apartment was brand new at the time, there's efficient AC in all rooms, the kitchen has everything you need, and the tower bedroom is to die for. The outdoor terrace was awesome with the private pool being a nice touch. Street parking is easy.
Our favorite thing was the street corner right below the apartment. Downright delightful. Calm, but always lots of people chilling outside the downstairs deli. Just watching daily life unfold from our kitchen mini-balcony was really nice and very relaxing.
The giant and lovely Maria Luisa park is about five minutes away on foot, with downtown Sevilla being at the other end of it (roughly 30 min from the apartment). Buses and electric scooters (Voi and the like) will get you there faster if you want to. A small grocery store is two blocks away and there's a giant modern mall a five minute drive to the south with pretty much everything you'll need.
Overall, we highly recommend this place.
