I've spent one week at Yulia's place. It's a little bit far from the centre but I knew this, at the same time it's close to metro station, nearest bus stop is in a few metres, 10 min walking to Barcelona Sants train station. Supermarket is in the same building, also you can find two bakeries there. The room was confortable and clean and it's quiet there. Yulia is very friendly and tries to help if there are any questions.
