It's a dirty place. But it's cheap and close to the metro. It's also a bit stuffy, because the only window that can be opened is a tiny one in the bathroom. But the wifi works and there's hot water. Plus, there's a convenience store right beside it, and a many excellent restaurants at the end of the block. If you're looking for nightlife, though, it's likely better to find a place farther south (e.g., in Condesa or Roma).
