The apartment was very nice. Rocio waited for us at the place even before the check-in time, which was greatly appreciated as we arrived a little bit early. We could also check out 15 minutes after the check-out time, which was great. Rocio showed us the place and the terrace, which was truly amazing with great views towards La Giralda. The apartment had all the important amenities and even some coffee, tea, olive oil etc. We found that the floor in the common spaces wasn't perfectly clean, but all in all the apartment was not dirty. The apartment is located in an old building, so they used the space in the best possible way. There was absolutely no noise coming from the outside, which is a rare find in Spain. Moreover, the location is just perfect - right in the heart of the city centre, but in a calm street.
What I didn't quite like was that Rocio booked us a taxi, which I somehow perceived from the conversation that would be cheaper that it actually was. Anyway, this doesn't have to do with the place itself, but just added to my overall experience.
We also had to use the air conditioning one evening as it was quite cold inside. Unfortunately, it did't work. It wasn't a big deal as it wasn't too cold, but it might be worth checking into this.
Overall, I enjoyed staying in the apartment and I would recommend staying there.
