The apartment was simply flawless. It was fully equipped, clean, two air conditioning (living room and bedroom), no noise neighbors or streets, location in the city center is amazing - sightseeing was easy and food Shopping with lidl close by (7min by foot) to perfectly live in Sevilla for some time. Parking 10min by foot if you are unlucky.
I would fully recommend this apartment and we enjoyed our stay a lot. 10/10 to make it more clear :)
Thanks also to Miguel for the flawless and fast communication (in English).
