Marieta is a really thoughtfull and helpful host. It's very nice that she provides breakfast. It's also pretty cool to have them in such a beautiful house like hers because you can feel like in a film :) Public places are cleaned every day.
My advise for travelers is to learn spanish a bit or always use google translator while communicating with the host because she understands english but speaks spanish.
Our room's window was to the inside of a house which means that we heard anything what people were talking while walking in the hall. Anyway, it was a pleasant stay and really nice experience to live for a few days in Seville, in such a beautiful spanish style house!
