We were a group of 5 and everyone loved the stay at Maria's place. It was the perfect place to get away from the heat and feel at home. The only con was the lack of place to park our car. However, if you don't have a problem with walking, you can easily find place to park 5/10 minutes away, and going to the center of Sevilla walking is also a very easy walk that's always worth it since the neighborhood is beautiful.
Maria was always extremely kind and helpful, offering valuable tips and answering as soon as we needed. Worth mentioning that she was flexible with our needs in regards to the check-out.
If you want a beautiful, spacious, nicely located and very clean apartment, this is the way to go.
