I have been to Seville many times, and I have tried many Airbnb.
Brad's flat however, is, hands down the best one. It feels very spacious, and is in a great good position to enjoy Seville. Brad is a great host, one you would love to meet more often. He comunicate in a timely manner, he gets back to help you in any question you may have (his restaurants suggestion is remarkable,) and he even managed to collect a package for us.
Kitchen was stocked perfectly with essential, drinks and snacks.
If you are reading this, just be quick and book, because you won't regret it
