Great walking location, close to everything we wanted to see. The apartment is tucked into an alley, and was quiet enough to sleep (we still used a sound machine).
Arancha helped us find parking, would recommend pre-booking a spot, it wouldn't been cheaper, and the first one we checked was full. Driving and parking were tough, as Americans we are not used to the European navigation and tiny parking requirements and it was stressful. But once the car was parked, we left it for 3 nights and about 60euro.
The ceilings are very low, especially in the bathroom. And as a couple over 6ft tall, it got to be quite uncomfortable to hunch over for more than 1 night. I wouldn't recommend staying more than 1 night to anyone over 5'9" tbh. Or if you use the bathroom during the night, the ladder to the bed is tricky in the middle of the night.
I didn't find the bed to be particular comfortable, nor the towels, but it was the same with all the places we stayed in Spain.
Overall we were happy with the apartment, coffee maker with coffee was a very nice touch that we greatly appreciated. Easy check in and out.
