Adam was very accommodating and helpful while my friend and I were in Barcelona. He gave us directions to get from the airport to his apartment, sent us a pretty detailed list of where to go and always answered our questions via Whatsapp in a timely manner. His roommates were really cool. They were available when we had questions, always pointing us in the right direction.
The apartment is right in the middle of the Gothic area of Barcelona. Hipstery, full of shops and museums on every corner. It was pretty safe, we never had a problem. The room itself was good if you are just planning on being out all-day. There is a great view of the city on the rooftop of the apartment building. We spent 3 days in Barcelona, we were rarely in the room. Great price for where it is.
