Cristina booked me a taxi from the airport to the apartment, so we came comfortably. She was waiting for us at home. She was so kind flexible! :)
My friend left her phone in the taxi, so she contacted the driver immediately to find it. really thank you.
The rooms and the bathrooms were all satisfactory. (One of the two rooms was cold when we stayed, but there were a heater.)
It takes 10 minutes from the house to Metro, and we usually took a metro or bus to go to tourist attractions.
If I go back to Barcelona, I will stay here~^^
