Alfonso & Guillermo’s place is a rare gem!
The location is totally amazing. It's a (maybe) ten minute walk to the major sites and attractions in town such as the Alcazar and the Seville Cathedral. It's located on a small pedestrian street off one of the more recognizable squares, which makes it easy to find even if you have a terrible sense of direction.
The neighborhood itself is full of small shops, restaurants and bars within steps of the front door, which really adds value as they were not nearly as expensive as the more areas around the touristy areas. My husband found a map of a Craft Beer Tour you could do around Seville and three of the bars where within 2-3 minute walk which is exactly what you wanted at the end of the day. Also notable, one of the top rated Churro's and Chocolate bars is within a thirty second walk (we swung by daily for our morning caffeine dose, but limited the churros to a last day treat), and there is an amazing Mexican place just down the way if you need a break from Tapas.
The place is fully stocked for basic cooking, so you don't have to eat out for every meal, which we took full advantage of.
Would absolutely recommend for a couple who like to walk and explore.
