I think this apartment is a great place to stay if you are out exploring Barcelona lots - it is a great location and a comfortable bed, and check-in and check-out was easy. Marianne is also lovely. While the room itself was super clean, the bathroom and shared spaces weren't as clean and if you're not a dog-person, then this isn't the place for you as the dog also jumps up on you etc. It was pretty stuffy because it's mostly an internal apartment but there was a window to an internal courtyard (which did mean it could get a bit loud though - the apartment itself too isn't very soundproof) and they provide a fan too. It was also cheaper than shared dorms where most people I knew were staying, so I think it's definitely worth it for the privacy and ease!
