The good: the place is well-located from a public transit perspective—you can get to pretty much everything easily. Very close to La Sagrada Familia, and having the backdrop of the church was nice. The kitchen was nice and the balcony was a cool hang out spot. They were also very good at responding to messages.
The not-so-good: the apartment just needed a little TLC (broken tiles, doorknobs, etc). We had a leak in the ceiling which ended up with a bunch of wet clothing—in all fairness, they did fix it quickly and also gave us a credit which was much appreciated, but we could tell it was an ongoing issue since the ceiling had a plate on it. Additionally, we were woken up at 4am by a neighbor drunkenly pounding on their door because they got locked out—literally thought someone was trying to break in.
Overall, we probably would not stay here again. The location was not our cup of tea and it felt like it was pretty expensive.
