Despite the fact that Ekaterina doesn't speak much English, we managed to successfully communicate through translation apps. She is a really nice host and was willing to host us late after midnight after we told her about our late flight. The window is facing the inner court which doesn't provide much air circulation or light but is acceptable. the bathroom is especially clean and tidy, only the noise of water pipes or from the neighbors are quite noticeable, especially in the morning. Maybe not for those who need absolute quietness for a rest?
The location is perfect. 5-10min away from metro station. The view up on the hills makes the daily walk out of the house to the nearby station interesting and enjoyable. It takes around half an hour to get to the city center. There are local supermarkets around the corner.
I wish all the best for Ekaterine and her cute little girl, would love to book again when I visit Barcelona again. :^)
