We stayed at Lucas' place for two weeks. We would stay again.
Pros:
Great location, close to lots of restaurants, bars, cafes, etc. Very walkable. And not far from other cool Palermo areas.
Good internet, no real issues with streaming or working with lots of video calls. I had to restart the modem like twice in two weeks, but it was fine.
Small kitchen, but equipped with the basics for cooking with no issues. Even had quite a bit of food and staples to start with.
Nice shower with lots of hot water.
Air conditioning and fan.
Quiet and secure.
Great communication with the host (we talked in Spanish, but I think he speaks some English if that matters).
Cons:
No real working space like a desk and desk chair if that matters. (although there is an area for one). I worked from the dining table area, which was less than ideal.
Kinda small, but certainly adequate for two.
