I traveled alone for five days in BA, Argentina.
Pros: Hotel was clean, the staff were extremely nice and helpful, and it is very centrally located, right on the Lima subtle stop. The continental breakfast was decent for 100 pesos, especially considering unlimited coffee. Thus, very basic amenities, excellent location, great service and cheap. I should also mention the building is quite old and beautiful.
Cons. The room and shower were extremely small, and there was no Wi-Fi in the room. There was only Wi-Fi in common areas, which were not air-conditioned.
Although sometimes I wished that I had spent more money for more services, it is hard to complain for $24 a night where I purchased it bundled with my airfare . I also tend to spend very little time in the hotel anyway.
