Paula's place is in a perfect location for a visit of all Sevilla by foot. Super easy to get everywhere. You can easily bike to Triana if you wish. The terrace is fab for a quick relaxation (though why bother doing this at home when you can go to any park or historic site around the city?!).
Paula also very thoughtfullly made all kinds of lists: restaurants, flamenco, sites to see, etc.
Basically this was as simple a situation as you want for a vacation!
