Inmaculada is amazing, and so is this place - I can't recommend it more highly!
I was worried that the photos looked too good to be true for the excellent price but the place is just as amazing as the photos make it look - it's a great value! The place was sparkling, and it's a perfect location if you want to walk all over the city and see everything.
Inmaculada herself is AWESOME. She's super friendly and helpful, and professional.
Also one small example of her going above and beyond -- I had asked her the best way to get to the apartment and she sent us the info for two options - bus or taxi - and provided the details and prices of both. When we arrived she was there waiting and noted that the taxi driver had overcharged us. The cab had started to pull away and she confronted him and though we weren't successful in getting the price changed, she even took a picture of his license plate and reported him to taxi authorities. She really cares about the people staying in this place having a good time, and she was upset that someone had tried to take advantage of us.
She was super welcoming, had lots of great suggestions for what to see and where to go, and even let us check out a few hours late. I would happily return to this place and recommend it heartily to anyone looking to have a great time in Sevilla!
