I booked this apartment for my parents, so this review is based on what they have told me:
They were welcomed by Beatriz's mother and everything went very smoothly.
They loved being away from the crowds of tourists and enjoyed having their 'little nest over the river'.
It was a little noisier than they were expecting - it seems there were some noisy neighbours at about 2am.
Overall it was a great and friendly experience.
Thanks for their introduction to Sevilla!
