Elena and Javi really went above and beyond for us. I forgot my clothes at their place, and they sent them to us (we paid shipping). We really appreciate their effort.
The apartment is in a great location: very near Hercules square which is where the locals hang out. Quality eat and drink for cheap at that and around that plaza. We never had to take any public transportation while staying in Seville.
The apartment is cozy and comfortable, on a quiet little street. We never wanted for anything. Highly recommended.
