Cool cosy apartment in a good location for tapas bars, little food market and supermarkets. Most sights in Seville are walkable but I'd recommend hiring bikes to get around as it is a very cycle friendly city. We hired from a local shop Bici4city which was very easy. The opening / closing times of shops and restaurants takes a little getting used to and planning.. for example, some attractions are closed on Mondays and Tuesdays.
There's also a local street market on Thursdays, selling all sorts..!
