I hope you don't expect a 5 star room with private bathroom for $15-20, right? It's nothing wrong with it. It's clean, the location is the best, you have everything you need - washer + dryer, 24/7 store right outside the door, 2 street food spots just few steps away, kitchen etc. It's good for visitors on a budget, who are gonna be coming back only for some sleep and shower - it's cheap and close to everything. Make sure you have some good ear plugs, drink a lot of mezcal and you'll be fine. If you're planning to stay longer for work or so and you're crazy about silence and privacy... maybe not the best option. Overall it's a cool and safe spot, have fun:)
