It was a great stay all in all.
The room was cozy & clean (bathrooms were cleaned by a cleaner every day).
The service was amazing - we were allowed to shower and leave our luggage at the hostel after check out. During the stay we could leave food in the co-workers fridge.
The staff at the reception was a great help in terms of information about Sevilla.
If we visit Sevilla again - we will definitely book another stay there.
Best value for the price in Spain so far!
