Mariano is an excellent host who communicated promptly throughout our stay. The apartment is in a lovely, authentic area of Seville and is impeccably clean with everything you would need and more. Me and my partner spent the week there working remotely and had no issues with the wifi as some old reviews suggest, it was strong enough for us both to be on zoom at the same time.
We especially enjoyed the view from the terrace and got a nice meal from the (very affordable) Chinese across the street one day and ate it up there overlooking Seville.
Would definitely recommend Mariano's place and I hope to stay again when I return to Seville
