La Joya is almost too posh to be called a hostel, with impeccably clean quarters, seriously comfy beds and the aesthetic of a Brooklyn loft. Attached is a hip bar and burger joint that's worth the visit even if you aren't staying. Friendly staff are eager to help with city info, and they occasionally organize barbecues on the rooftop deck.
Its location near the bus station makes it convenient for those arriving late or departing early, yet inconvenient for quick trips to the most popular cerros.
