Rafa answered quickly during the whole process. He even wrote to us on his own initiative a couple of days before our stay to inform us of the best way to get to the apartment from the airport.
We got a bit delayed by the traffic, but when we arrived, Rafa was still there and welcomed us warmly. He showed us the apartment and gave us tips about the city. He insisted that we could contact him if we needed anything (which we did not, as everything we needed was available).
The apartment itself was exactly what was on the photos, with maybe the tiny exception of the ceiling of the second floor being a bit low (around 190 cm). This was not a big issue as we were only on that floor to sleep and use the restroom.
The location is also ideal for tourism, as the main attractions are at walking distance, meaning less than 30 minutes, around 10-15 for most.
Overall, I don't think you will be disappointed by renting Rafa's place, as everything was pretty close to being perfect.
