Carmen's apartment is situated in just the perfect location , in less than 5-10 minutes' walk, you reach almost every historical site you need to visit in Seville. The further ones are a mere 20 minutes away, and very accessible.
Carmen's daughter helped us with our check-in, and she gave us several restaurant recommendations. We tried 2 of those, and both were some of the best meals we had in Spain. These are not restaurants that are ranking at the top in tripadvisors.com, but are non-touristy restaurants that serve food that feel like was made in grandma's kitchen, very authentic and very nice.
Carmen also helped us with calling a cab to the train station on the day of our check-out, this was extremely helpful of her, thank you Carmen!
As for the apartment itself, it is just like the photos shown on here, nothing more and nothing less. Oh and there's a roof top terrace that you must go if you wish to see the sun setting over the cathedral ;)
