The apartment itself was just like in the photos, as well as right across from the station, and the city center is only a 5-10 min walk. There were, however, some things that we were not satisfied with.
Some weeks before staying here, we had contacted Lucas ask whether it would be possible for us to drop off our luggage in the morning, as we would arrive hours before check-in time. He assured us that would be possible. Upon arrival, we messaged him and had to wait for a while in the heat before he replied that we would have to wait until the cleaning lady arrived (2 hours later). Overall, Lucas was quite difficult to get ahold of, as it would always take a while before he replied. Moreover, we have never actually seen him, and the cleaning lady was the one who explained the apartment to us. She was very nice and friendly, but only spoke Spanish.
In the building's stairwell, there was a constant and intense sewer smell. As for the apartment itself, it was nice and clean, but one toilet wasn't really working, the light in the other bathroom didn't work, and one bedroom didn't have airconditioning. Moreover, the wifi wasn't working; we couldn't find it and the provided password didn't work for any of the available connections. When we messaged Lucas about the issues, he said that he could send someone to fix the lights, but that "weekend is not the best time," so he didn't. The wifi, he said, should have worked after unplugging and plugging the router in again, but it didn't.
All in all, the apartment was not great, but I guess that's understandable for the price. Quite frankly, we were disappointed by the reachability of the host, and were surprised that we never once got to see him.
