We really enjoyed our stay at the apartment of Corralito! It was clean, beautifully decorated and at a very nice place in the center of Seville. The apartment has everything you need. That also includes good WiFi which was a necessity for our two week long workation.
Next to that the communication with Corralito was very nice. He responded quickly whenever we had a question, and gave us a few recommendations (La Duquesa was a delight, thanks again Corralito! :)).
If you are going to visit, then also make sure you visit Maravilla (a nice bar with great sangria and breakfast), Borbotea (a good coffee place) and El Rincón Sagrado (wine bar). They are all located in the same street as the apartment which is great! We really enjoyed ourselves there after a days hard work! :)
All in all we would definitely recommend people to stay here!
