Everything was perfect at Luisa's place. The room was very cosy, clean and confortable. The location is a bit far from the city center but it's very easy and fast to go there with différent buses! Luisa also gave to us a bus card to get 50% discount on every bus trip!
She propose to take us directly at the airport when we arrived for only 10euros and we get a lots of tips to visit Sevilla from her.
I definitely recomand Luisa's place. I will come back there next time.
