pro: the apartment is in a great location. it's very central and close to the bustling Bellas Artes area, with lots of bars and restaurants. it's also very close to the metro. communication was good (note you need some Spanish to communicate as the staff don't speak any English).
Con: the apartment is quite run down and not very clean. it needs a refurbishment (broken cabinetry etc) and a thorough clean (soap scum in bathroom, grimey walls etc). it's quite a dark apartment. It's a bit complicated to get in to the building as you don't receive a keycard when you check in(we were at the mercy of ppl opening doors in order to get in).
