Paul & Mariana are nice, they live on the ground-floor of the building and respond quick to enquires.
The location is great, 20min walk from the city center, in a location with a lot of restaurants and bars and a great farmers market close by.
There are major renovation works in the building next door and they start digging with an excavator at 7AM. It was not a problem for me but it could bother you if you like to sleep in.
Check in and check out is done by another guy, not the most friendly or helpful type, but it shouldn't be much of an issue, you get to see him only twice.
On the whole, I would recommend the apartment.
