This apartment is owned by a private company who use Airbnb to advertise. It is a nice apartment in a good location BUT the check in process was ridiculously overly complicated.
We had to fill in a form with everyone’s details, passport numbers and issue dates etc. After this we had to send pictures of the passports. All of this was supposedly to get access to an electronic key. For this we had to download a specific app. Once this was done the electronic key was issued. However this didn’t even get you into the apartment. You still needed 2 more physical keys for this. Only one set of keys was provided. For an apartment that sleeps 6-8 adults this is not good enough.
There were no towels in the apartment. They did deliver them after being contacted but not before one of us went out to buy 6 towels.
The air conditioning broke on the second day - no sleep for the rest of the weekend as the temperature in Barcelona was 29-30 at the time.
The private company insist on contacting you privately so you have to give them your phone number etc. This is outside the rules of Airbnb.
As I said, good apartment, good location but the whole process was not easy at all. Shame.
