We would 100% recommend staying at Luis’ place. The room is a good size and comes with a private bathroom and the apartment is generally very spacious. The terrace is huge and a great sunbathing spot with views of a lovely big garden.
Although the walk to see the main sights of Seville takes around half an hour, I would recommend this location because it is right near the alameda in which there are lots of great restaurants and bars. You can walk into the centre of town along the river too.
Excellent value for money and I would definitely visit again.
