The apartment is conveniently located not 15 minutes away on foot from the main train station, and was exactly as described. The access was uncomplicated despite the appearances at first (going through a door from the nearby restaurant upon arrival, using a smart lock to open the apartment door), but all steps were clearly described and everything worked fine! I did check-in at 11pm, so I would suggest contacting Jorge if you plan on arriving later, in case the restaurant is closed though. Not that it mattered in my case eventually though.
I think it's worth mentioning that the apartment was, so far, the cleanest and tidiest I had the chance of booking on Airbnb. Although I did not use the kitchen, it was large and looked fully equipped. As I had a to work one day, the wifi was fortunately very speedy (up to 200mbits/s download), which shows that Jorge did not leave any detail up to chance. So definitely a recommendation from me for a short or even a longer stay.
