We really enjoyed staying at Alberto's place and would highly recommend it. The communication was easy and we could check-in a bit earlier as well as use garage what is a huge plus if you visit Seville with your car.
It is 5min walk to the city centre and just outside you could find anything you need for your stay from local Tapas to Flamenco shows. Triana neighborhood is very charming and gives you an opportunity to be the part of this local community.
