Emilios place is located very central in the oldtown, only a 10 minute walk from Giralda. The apartment is very cool - a 4x4x5 cubic room, with the bedroom on an upstair Gallery. You reach the apartment over the most beautiful cortyard i've ever seen.
There are a lot of nice possibilities to eat & drink around the aprtment.
I recommend strongly to listen carefully to Emilio's recommendation for Tapas bars :-)
