The apartment is as described. Very cute, clean and in a great location situated in the historic part of town very close to the Cathedral of Seville and Alcazar. The beds were comfortable and the aircon was great as Seville can get very hot during the summer months! One thing to note is that the apartment is on 2 floors and the staircase is quite steep so it would probably not be suitable for families with very young children but it was totally fine for us!
The check-in process was a little stressful, we had to wait a while to check-in as the previous guest had a late check-out. Luckily there are restaurants near by the apartment so we could wait there with our suitcases.
Things to expect upon check-in: you will be asked to sign a standard form (which is in Spanish) and provide copies of your passport. We unfortunately don't speak/read Spanish so the process was a little confusing as we weren't sure what was going on. However, upon conducting a google search, this appears to be compliant with Spanish law in Andalusia.
Overall, our stay with Maria was very nice and we would recommend this place. Thanks again Maria for being so hospitable.
