Essentially this is a very good place to stay in Sevilla. The location is great, not right in the touristic region's centre, but comfortably at a walking distance and with a nice city landscape to enjoy during the walk, crossing the Guadalquivir river in the way. The 24 hour reception makes it really practical for one's arrival or departure. And the big supermarket right beside is also an advantage. There are also some cafes / restaurants around for enjoying breakfast right away or a meal right before getting to the place.
However two details should be taken into account and if possible, fixed. It is true, as other reviews mention, that there is a bad smell in the bathroom. This seems to be a structural problem, some pipe must be not working very well, for the bathroom and the whole apartment were really very clean.
Also, the wifi connection is not reliable. It is weak, but every now and then it was just not possible to connect. In a traveling context, this hindrance is uncomfortable.
