Emilio's place is a wonderful option for being very much in the heart of Recoleta. You're not more than a 15 min cab ride in any direction from somewhere exciting. And what you do have in walking distance is also great, with many big avenues nearby full of stores, bars, and good restaurants. It's basically very nice without feeling like you're removed from how the locals live. You can still feel that in the neighborhood.
The apartment itself is great. The views from the balcony + the terrace are big pluses, knowing you can get the fresh air and relax with a beer whenever you want. Of course it also gets so hot here in the summer you may only be enjoying them early morning or at night! haha The parilla is awesome and made for a really nice night with friends.
The place is cozy and the tv works great, it's nice that it extends off the wall and plays any streaming app you likely use. Kitchen is good, no complaints there. Same with the bathroom.
Overall, I think the place is really good for staying in. I'd recommend it and the area it's in.
