This apartment is very much a boutique hotel.
The place has been recently renovated, and you can tell they spent money on it. The beds are super comfortable, the showers are great, the towels top-notch. The design, with the exposed concrete (and its imitations), is also very nice. There's a good dishwasher, an even better washer-dryer and, to top it off, all the household basics you need. And whatever we missed, like plug-in mosquito repellents, was promptly provided by the hosts, who were available and helpful throughout. They even gave us a second travel cot, which we depended on but is generally hard to find. Finally, the apartment is in a great location, right between bustling Palermo and more chill (but no less exciting) Chacarita. The entrance is on busy and fairly ugly avenue, but since the apartment itself is the last inside the block, all you hear is the humming of surrounding ACs and the occasional car honking.
Now to the downsides, which you may care about or not, depending on preferences.
We stayed here with two small children, and it wasn't as ideal for us as we'd thought. The living area was smaller than expected. The kitchen has all the basics but you can tell it's not really meant for much cooking. And since the apartment faces south, it never got any direct sunlight, which may be an advantage in the summer but in autumn meant it was a little cold and humid and we weren't able to use the courtyard for our children to play. Overall, it wasn't very cosy.
So maybe this isn't such a good place for a family, but I'd really recommend it for a bunch of friends who want a *really* nice crash pad in a great location.
