Francisco's apartment was just perfect for what we wanted. Located at Pacifico area is close enough to the center so that you could walk if you wanted (~10min by public transport) and yet far enough so that is quiet and separated from the "fuzz".
In terms of equipment this is the best equipped apartment that I have been in for quite some time. Has anything you need and more. For example, fully equipped kitchen, plenty of toilets and bed clothing, etc. In general, there is nothing missing.
And finally, super clean, well maintained etc. We were 6 (3 adults and 3 children) and we really enjoyed our time there. Highly recommended
