Antuan sent me a message with detailed information about the transfer from the airport to his Metro station. He picked me up there although my plane had a delay and it was quite late. He even carried my suitcase to his apartment. The Metro station is just 3 minutes away.
The room is little, it has a bed, a shelf, a little wardrobe and a desk with a chair. There is also a ventilator, but I didn't use it. I got one towel from Antuan and he told me of a nice spot around his area. I also had the possibility to put something in a special shelf in the fridge. He was very friendly and although he speaks very little English, we could understand each other. I also got to know Maite, his wife or girlfriend, she was also very friendly. That was the last time I saw Antuan until I left Barcelona. If you don't want or don't need to talk much to your host (like me), it's perfect with them because they let you do your own things and you always have your privacy.
One thing confused me a bit and I think it should be mentioned to the guests: there is another room mate opposite to the guest's room and it could be possible to see him more often than Antuan.
It's also noisy as the neighbours have a very young child which talks and cries a lot.
I will book this apartment again if I return to Barcelona.
