This cozy apartment is clean, well equipped, and close to restaurants, bars, shops, and all the tourist sites. Moreover, Jose Luis was extremely friendly and welcoming. He met me at the apartment and took time out of his busy schedule to give me a breakdown of all the places I should visit in Seville (including restaurant recommendation). I highly recommend this place to anyone visiting Seville.
P.S. the only downside was that the internet is slow. So I wouldn't advise if you're planning to get work done on this trip.
