The place is small (perfect for 2 people), very nice and cozy, and it's in a very strategic position for visiting Seville (the cathedral, plaza de Espana and the Alcazar are all near). The house had everything we needed (towels, coffe etc) and was very clean. I also worked remotely from there a couple of days, and it was a good experience.
The street itself is nothing special, but there's a very good tapas bar right at the corner that you should definitely check.
A minor thing of the house is that it's at the ground level of a narrow street, so the light comes in only at certain hours and you generally want to keep the curtains closed. A part from that, we had good stay and would definitely reccommend.
