I can only recommend staying with Luis and his girlfriend Rosa. They are very nice, openminded people and will do their best to make you feel at home. When we arrived, Luis showed us the whole (very beautiful) house and everything we needed to know, gave us a card from the city with lots and lots of tips together with a guide of the city he has written by himself (lots of extra info!). The room and the rest of the house were very clean and neat. I especially liked that the whole house is very colorful, with lots of photography and art hanging on the walls.
On the upmost floor is the terrace. It is covered in plants and has a table to sit around comfortably (at least at night, it can get really hot in Sevilla in general!).
Then last but not least, if you're a doglover, there's no way how you could miss meeting their dog corfu. He is such a sweetheart, loves to play (and to lie around) and is simply one of the nicest dogs I know, I instantly fell for him.
Thank you very much for letting us stay with you!
