Luis apartment is fabulous. It's located in a quiet street in beautiful Triana and is very peaceful at night. Its is right next to Calle San Jacinto where there is a buzzing atmosphere with lots of shops, cafes and bars.
The apartment is modern, scrupulously clean and has every facility you require.
Luis is a very kind host, who communicated quickly and allowed us to leave our luggage early.
Seville is a beautiful city and the Triana area is a great base.
I would highly recommend Luis' place.
