The parking space is the best. We did not have any problems with the parking spot or other cars, although you need good driving skills since it is very tight.
The room was okay, nothing special. The light was dark and for someone who is taller than 1,80m the bed might be to small. (I am 1,87 and my feet sticked out).
In the room everything you need is there. In 15 min you are in the center of Sevilla on foot.
