We stayed in this apartment at the end of February 2020. To start with 'Juan' is not a host, this apartment is one of many managed by a company named Valencia Guest.
They asked me at what time I was arriving to Valencia to have an employee to meet us there. I told them the time my plane was landing, and so they told us they would meet us 2 hours later from that landing. When we arrived, the taxi told me that it was a 15 minute ride, so I called the number they had provided, and of course, it was not office hours. So we had to stay at the airport (I preferred that to being on the street) for 1 hour and a half, with no one contacting me.
The employee who came to open the door, didn't even have the codes. I really believe they hire students or people that are not interested in hospitality as you would expect at the reception of a hotel for example.
Then I asked for another key (we were 4), and they couldn't give us another one.
I had read the reviews and seen there is an issue with hot water. There is a switch above the hair dryer, that can be easily confused as being a switch to it. It's written On/OFF but no reference to leave it ON so you can have hot water. Surely Valencia Guest is not reading the reviews. Such an easy fix to an issue that was reported many times.
No WiFi at all.
And it was really cold when we got there, and the only way to heat the apartment was leaving the AC on the whole day. The floors were so cold.
My lesson learned is that I will never ever stay again in a AirBnB that is not really hosted by a host. When I have an email from a company, I will cancel it immediately, I prefer going to a hotel where you can ask thing to humans, and not students making pocket money by phone!
