Castro offers a variety of affordable choices, mostly along San Martín and O'Higgins, their immediate side streets, and the eastern end of Sotomayor, which turns into the wide concrete staircase called Barros Arana with a high concentration of hospedajes (budget accommodations). Numerous boutique and top-end offerings are housed in palafitos, especially on Ernesto Riquelme and on Pedro Montt.
