I enjoyed staying at Alex's place. My experience started with a warm welcome at check-in and a very nice room to sleep in. I really appreciated a thoughtful touch, signs on the bathroom doors that could be flipped to read "occupied" or "free", so I wouldn't have to concern myself about a knock on the door. I enjoyed walking past the nearby large park and seeing people play ping-pong on some outdoor tables every day. Metro transportation makes it easy to get around the city by buying a 10-ride ticket and validating the ticket each time I board a subway or bus, but the central location also makes it easy to walk to interesting places too. I particularly enjoyed the Museum of Catalan History on the waterfront 10 minutes away across the park.
