An excellent Airbnb (one of our favourite airbnb experiences so far). Kat and Piero are quick with their responses and helped us organise an earlier check-in. Although the internet had gone down (due allegedly to the provider), Kat and Piero got a new connection for the flat asap, and they also dropped off a better air-conditioning unit, some more kitchen utensils (that we had requested) and even some supplies! They were very polite and courteous and mindful of our needs.
The apartment is trendy, comfortable and has a good view. The balcony was a perfect place to eat dinner and the kitchen was easy to cook in. A couple of supermarkets are just downstairs and the main plaza and city center are 4-6 blocks away. Santa Ana metro is 1 block around the corner. There's a square with some playground equipment and food trucks a couple blocks down Santo Domingo too - good for small kids.
Highly recommend this airbnb over many others in Santiago!
