When I booked my trip to Barcelona, I loved that Arthur's space had a beautiful view of Sagrada Familia - little did I know then that it was the best view in ALL of Barcelona! I've traveled to BCN many times and my normal booking spot was taken - and thankfully it was! Checking in was a breeze. We were given multiple options for food (including the really great restaurant also owned by Arthur [that you MUST try!]), sights to see locally as well as a map of the city.
The apartment was VERY spacious, bed very comfortable, temperature just perfect, strong wifi, and (again, it must be stressed) the view! You will want to just stay in the apartment all day and take it in. Seeing people at the Park below taking photos all day long. Local musicians playing near by. It's all very beautiful.
There are a lot of stairs for anyone who might have issue with climbing. It was exercise for me. Also had the pleasure of meeting Arthur and his staff and everyone was exceptionally kind, warm, gracious, and certainly a place that deserves my strong recommendation! Thank you Gaudi's Nest Team!
