I toured this hostal a few months ago. You can't beat their location. Tapas bars are everywhere, jazz, good food, arts and shopping.

It is a big hostal, reception desk people were friendly and promptly sent me over to see the rooms.

I choose not to stay at Persal because I observe, during my frequent stays at nearby Hostal Adriano, that they tend to deal with groups in and out and as a former travel agent,I learned to stay away from hotels/hostals that take groups to guarantee my peace of mind and tranquility during my stays.

If you are not bothered by this dynamic, it is a nice place to stay.

Happy travels!
