This apartment has some nice things that I will mention in the end. However, one really bad thing that could have been a very real problem if we stayed an extra day like originally planned.
My husband works remote from the USA and needs internet. Plus as tourist with American phones we need internet for directions, upload photos to Google Photo, etc. The internet in the apartment does not work in most rooms and is very slow in the small bedroom near the door, it did not upload our photos. We spent a lot of time in the stairwell outside the apartment trying to get internet, but even that was slow. It was a blessing that my husband had the intuition to cancel our last night and drive to Córdoba, where our AirBNB in Córdoba has excellent internet.
There is a little mold in the bathroom and the hot water last for a very short time. Only enough for 1 person in our 6 person family to take a shower.
Parking nearby is 33 Euros which is very expensive. Like staying in New York City.
The kitchen is well stocked with Olive oil, salt, pots and pans. The washing machine/dryer was nice to use. However, we had to turn all the breakers on and off to get it to work.
And of course, the location is wonderful with easy walking to most all tourist attractions.
The internet and not being able to take a hot shower is the reason I gave it a three.
