Wow, our stay at Marieta's house was perfect! If you plan on staying in Sevilla, stay there! The house is very beautiful and the room lovely. There's a living room and a backyard which you are allowed to use, and two shared bathrooms. If you need to use the kitchen, you can just ask Marieta. She provides breakfast, too. There's a dog which is cute and friendly.
Marieta is incredibly friendly and heartful, especially if you speak a few words Spanish. She responded quickly and gave her best to make our stay perfect.
