We had a great time at Ale's place. It's really beautiful and spacious, and pretty much exactly what we expected. The neighborhood is lovely and central, and perfect for exploring. We traveled by foot and UBER, which was super easy, but there are bikes and scooters for rental on nearly every corner nearby.
It was pretty chilly in the apartment so we appreciated the large space heater in the living room. Street noise isn't too loud, but the bedroom is adjacent to the front door of the apartment building. Early in the morning we could hear the door opening and closing loudly. So pack earplugs if you're not a heavy sleeper. There are a couple families in the building too, and they were pretty loud (you can especially hear them in the living room with the super high ceilings). Again, earplugs are helpful when sleeping. Otherwise I didn't think the noise was much of a problem.
Overall we had a great stay!
