Natalia's place is very well located, close to the Cementerio de Recoleta, with bus stops and subway stations nearby. The apartment is clean, comfortable and well suited for couples, with everything you may need for short-medium term stays.
We had a little issue with the check-in, since we informed our arrival time (at night) in advance, and notified the host when we arrived at the airport, but she sent a last-minute message notifying us that we should pick the keys of the apartment in someplace else. Fortunately the taxi driver allowed us to use his internet signal to look for the address and her message came in, but otherwise it would be convenient to arrange those things in advance.
Although the check-out time was around 10am, she allowed us to leave our baggage in the apartment for some extra hours (until we departed to the airport), which allowed us to go sightseeing more comfortably in our last day, so we are grateful for that.
