I stayed 15 nights at Ruben's place and I did not feel any difference from being home.
The apartment is spacious and has a perfect location at the diagonal street, close to Sagrada Familia and the metro station. Located in the heart of Barcelona with a quiet neighborhood. Clean and quiet renovated apartment, has all what is needed to spend a relaxing stay and work remotely if required. 2 toilets with a fully furnished kitchen that you can use anytime. Nice balcony with a view and a nice living room. As for Ruben, he is supper nice and friendly. He welcomed me after midnight and helped me with my bags from down the street. He gave all the required information and was always available for help and to guide. A welcoming friend that I personally did not experience a better welcome before. Finally an advice from a person who visited Barcelona more than 5 times, Ruben's place is the best place to stay at for a really good price. <3
