We only spent one night there, but unfortunately it turned out to be quite noisy. This was our first night in Barcelona before heading to Sevilla. The staff were excellent and the room was clean, but the noise was a problem. Our room was located inside the building, and it seemed all the water pipes ran through this particular room walls. Each time someone upstairs used water or took a shower, we could clearly hear it rushing through the pipes, and it was very loud. I had trouble sleeping, though my kids weren’t bothered by it.
I would still recommend this Hostal, but suggest requesting a room that isn’t on the inside of the building. Perhaps one facing the street might be better—though there could be traffic noise to consider as well.
