The main problem we had was the arrival/accommodation. Since our plane landed about midnight we couldn't make it there before 1 AM next day. Mariona informed us that she will be away on vacation during our stay and that her brother will take onto accommodating us. Two days before the arrival, she let us know that the brother will have to take taxi 2 ways from his late night's work and that the total extra cost that we would have to pay to him was 40 EUR. It did not sound logical to us, but two days before the trip, we had no way of arguing. Different places may have different standards, but after we paid the brother and were let into the apartment and alone, we realized there was no soap in the bathroom (~2AM). That was a bit too much. Fortunately there was some leftover of a manual dishwashing detergent to mitigate the situation.

In general, the apartment is well equipped with appliances, but if you look for detergent leftover, there was none. We had to buy both the dishwasher and the laundry detergent.

The apartment pretty much matches the description. It is located very close to Metro and offers a lot of room. For parking in the building, Mariona asks for another 12 euros per night, but if you know Barcelona, you surely realize the car is not needed unless you plan to go outside of the city.

Internet is crappy, but who cares if it does the trick (with some frustration, though.) It is actually a handy 3G to Wi-FI hotspot you can carry with you around the town, and it works somewhat better in some locations.
