I initially booked another property with the hosts. It was a bit noisy, but after contacting the hosts, they graciously moved me to another apartment. This building wasn’t soundproof and I can usually sleep through anything.
I couldn’t have been happier with the next property! The apartment was spacious and modern, and very quiet. It’s within walking distance of all the sites (cathedral, Alcázar, etc.) and a short walk (20 minutes) over to Triana. The hosts didn’t cut any corners with this property! I’d definitely recommend it.
