I had a great stay at Pepi's place. While reviewers aren't wrong that it can get a bit noisy at times, I didn't find that to be the case in the bedroom. It's of decent size but only has a window to the building courtyard so is both dark and quiet. I found the place perfectly located: if you walk south you immediately get to one of the main shopping streets which takes you to the cathedral and all the other main tourists sights, going north takes you to more locals tapas places and late night bars, along with one of the main markets. I also ran into a street flea market. Definitely a worthwhile place to check out Seville!
