Awesome location! The neighbourhood is nice with cool bike shop, record shop, and the best optician (with unique sun glasses). And lovely restaurants like "Maquita bar" and "La Fabrica de Besana". You are close to main shopping street. The cathedral and alcazar is in walking distance (15/25 minutes).
The apartment is spacious and clean, it has a good washing machine and the ironing thing also works very wel. The shower has good water pressure.
The only thing I can think of that is good to know is that the airco is in living room. At night it was a bit warm in bedroom. But there is also a bed in the living room so I think you can also choose to sleep there :)
The communication before arriving and during the trip was very good. The car parking was perfect so our car was safe while we enjoyed lovely Seville! We'll definitely come back and would stay again at this Airbnb!
