I had a fantastic stay in Sebastián's flat. The rooftop terrace was a lovely place to have breakfast (thoughtfully provided by Sebastian, an excellent host) and the entire place is kept very clean with all the amenities you might need. It was nice to wake up and see the sun rising over Barcelona from a comfy bed. The location is quite convenient to many shops and restaurants & is perfect for walkers- I walked to Las Ramblas, the Gothic Quarter, Museu Picasso within 10 - 20 minutes & La Sagrada Familia, the Csstell at Montjuic or La Barceloneta in around 40 mins. Definitely recommend!
