Felix's place is a wonderful apartment very near the river. It is a short walk to restaurants and bars and beautiful views - we primarily walked around Sevilla during out stay and found that very enjoyable, though public transport options are also available (and may be preferred during hotter weather).
If you are driving a car and unfamiliar with Sevilla, be aware that Triana is an old neighborhood with narrow streets and few parking spaces. There is a garage just a couple blocks away, but I didn't find it until Felix gave me directions - you may want to plan a little extra time for dropping off bags, then parking and walking back. Fortunately for me, Felix was very patient and helpful, even though I missed my ETA by an hour due to a few wrong turns and the search for parking.
