It was really a joyful, and valuable staying with Rosa at Barcelona. She contacted me the day before I came to make sure everything and provided very clear information about transportation.
Her house is located in a quite and safe neighborhood and only 5 mins walk to metro station, 15 mins walk to Sangrada familia. It's an extremely clean and super cute house.
She was very sweet to provide a welcome dinner which comforted me a lot (I was so sick when I arrived). And she also prepared coffee, tea and fruits in the other days.
She is always so kind to provide information and respond any question, even accompanied with me to a flea market!
You cannot miss the chance to stay with Rosa if you go to Barcelona!
