No surprise when you arrive, the photos are just reflecting reality; the flat is small but very functional and very well decorated. The A/C was on when we arrived (thanks Joaquín) and we used it a lot during our stay. The terrace is really nice if you find the time to enjoy it between all the sightseeing. Joaquín was really kind and it was easy to communicate with him. He was flexible with the departure time and offered tea and donuts as welcome gifts.
If I really have to identify areas of improvement I would say that the water pressure in the shower was a bit low, and for us, as we stayed only 2nights, it was not as centrical as we thought.
So to conclude, very good experience! thanks Joaquín!
