The atmosphere and location of the apartment if just wonderful. I chose Nené’s place for the sunlight and I was not disappointed. I really enjoyed standing on the balcony looking out over the city. You have a clear view of the cultural center where live music plays on Thursday through Sunday evenings, and the sky is beautiful at dusk. The windows are north-facing, which means you have a consistent level of sunlight throughout the day and it doesn't get too hot inside.
The building is also very easy to find, has 24-hour security, and two elevators for quick and accessible access.
There are many amenities close to the apartment so you don't have to go far to get what you need. There's a cornershop with basic food and house necessities one block south, a liquor store one block north, and a supermarket four blocks east. The areas also felt very safe to me and the locals are super friendly.
For the host, Nené is a really wonderful person who's warm and communicative. She was very welcoming, super helpful, and just a joy to interact with. She was also very helpful and gave great advice on what to see and where to buy gifts to bring back (I was specifically looking for Chilean wines, and she pointed me to a boutique that had just what I needed).
There are two small issues that are fine if you're prepared for them, so I wanted to mention them here for other visitors. 1) The people who work the front desk don't speak English, so if you're a traveler with limited Spanish (like me) and need to talk to them, come prepared to say what you need in Spanish. 2) The balcony doors don't block sound completely, so if you're a light sleeper, bring ear plugs as there is inevitably noise at night that may keep you up. (I didn't personally find this to be much of a problem, but I can imagine it being as issue for others.)
I stayed at Nené’s place fo two months and would gladly do so again. Happy travels! <3
