Antonio's apartment is a great place to stay in Santiago - close to the metro and cafes, restaurants, a small park, shops. The bed is comfortable and the shower is hot and powerful. The kitchen has everything you would need to cook a meal (although I did not because of the local restaurants!). It is secure with easy check in (24 hour manned reception for the apartment building).
I stayed for a week and the size of the apartment was great for that and having the balcony to relax on as well as a comfortable sofa inside was brilliant. Wifi and table were good for working.
Antonio arranged a taxi pick up and drop off for the airport and other taxi journeys I needed which was very easy and worked well.
Two minor downsides - the traffic is noisy and the spiral staircase is narrow which might not suit everyone. But these are minor, overall it's a great place to stay.
