The apartment is located in the heart of the Seville city center, and is a perfect location to explore Seville's highlights all on walking distance. It is very spacious and tidy. Communications with Maria went very smooth. She even helped us arrange a parking spot (which can be a challenge in the city center!).
Reaching the apartment by car is quite an adventure as the streets are narrow and mostly one-way which makes you circle around the center if you miss a turn. But just stay calm and try again, you will find it in the end ;-).
And about the noise from the street: yes you are in the city center of a lively city!!! We were with 3 young children and just made them tired enough during the day to make them sleep through it like a log..... :-)
