The apartment was very clean and comfortable with everything we needed.
The location is incredible, in one of the busiest areas of the city. Despite this, the apartment has excellent soundproofing and therefore we heard almost no noise from outside during the night, which allowed for a good rest.
Communication with Rocío and Juanma (who welcomed us) was great. We received great tips about gluten free restaurants, bakeries and stores, which was extremely helpful.
Note: the apartment does not have a lift, and it is on the first floor. It wasn't a problem for us, but it might be for someone with mobility issues, or lots of suitcases.
