We had a short stop-over in Seville and enjoyed this property for only one night. In terms of convenience, it worked out really well—it's in the center of town and very walkable to a lot of Seville's many touristy areas, including the cathedral. The host and her assistant were very easy to get ahold of, and answered all of our questions as we coordinated check-in/check-out.
My only complaint was that we felt slightly misled by the first floor "bedroom area" description and photos. To be clear, it's a living room style space that travelers will pass through on the way between the other floors and the townhouse entrance. The photos obscure the stairs that lead to the next floor, and thus it's important to note that there is no privacy door between this and the second floor living room. Definitely not a deal-breaker, but it is a bit of a hassle and I wish the photos properly documented how this floor connects to the rest of the house.
All in all, we had a great time in Seville and were happy with our stay.
