We stayed here for a week. It was great! The location is really nice if you're looking for a neighborhood feel, plus it has GREAT access to Montjuic, which was so nice. There are tons of great places to eat and drink right outside your door — we loved Bar Seco, and of course there are tons of places on Blai right around the corner. The Parallel train station is a short walk.
Inside the apartment, we were really happy with how clean and spacious it was. It might be a little tight for two couples, but for just two people, it was perfect. Loved sitting on the balcony every day for some fresh air and neighborhood sights. Nice TV and couch to lounge on when you need some down time. Didn't do any cooking, but the little kitchen is cute and nice. Bathroom is fine. Really appreciated the ceiling fan in the second bedroom! We felt safe, clean, and well taken care of. Juan Carlos was super easy (and fast!) to communicate with.
Would definitely stay here again!
