The listing is correct and very accurate. Very clean. Javi is very accessible and quick to respond with help, answers or questions. If he doesn’t have an answer he’ll try to find out.
As for location, the description is correct. My only suggestion is if you are like me, walking everywhere to enjoy the city on foot, and your interests are largely in the historical area then you may want to find an apartment closer. Completely doable, don’t get me wrong, but sometimes the extra stretch of walk on the pavers was hard once you’re tired. It all worked out and I often just planned my day always heading back towards the apartment.
That’s it, had a great time and Sevilla is as beautiful as you expect, the people are great as is the food and drink, and it is very safe.
