Great experience in Sevilla! You really could not ask for a better location. The train station is walkable (if you don't have a ton of luggage) or easily catch a cab. You are surrounded by all of the tourist attractions and a short walk to Triana across the bridge. Jose Luis provides some great recommendations when he welcomes you to the flat and highlights everything you need to know about the city on a map he provides. The time he spends going over everything and answering any questions about the city is a great touch. The flat is on the top floor so there are quite a few stairs to the top - just to keep in mind if this would be a problem for you.
