I spent 4 weeks at Antonio's place in the middle of Chilean winter. Location is superb, in the best part of the city and a 5 minute walking distance to metro station. The place is spacious and well equipped, the views are very nice (unfortunately Santiago's infamous fog spoils them a bit in winter). Internet was fast and reliable. The heaters were generally sufficient, though as the temperature in Santiago drops sharply after sunset, during the cold evenings it would take some time for heaters to "catch up". At night it was always OK with the provided blankets. The lighting on the first floor is a bit dim and can be improved. Also, having the TV set on the second was a bit unfortunate for me, as there's a comfortable sofa on the first floor which is where I would like to watch it. Antonio is a great host, he speaks good English and was very helpful and responsive throughout the stay.
