Me and my girlfriend had an wonderful time during our stay in Barcelona. The apartment was very comfortable and bright and it was fully equipped including a hairdresser and an iron - rare thing.
The neighborhood was so beautiful and sometimes we felt like we were locals (Holla!). Close to the house there was a mini market and a lovely bakery - try the croissant chocolate - as well as the famous park Guell. Also, the metro was literally meters from the house.
The only disadvantage is that the area of the apartment is far away from the center of Barcelona. Everyday we had to spent about 30 minutes in the metro in order to go to the center and another 30 minutes to come back. In addition, we couldn't go to the city for a few hours then come back to the apartment to rest and go out again for a late night drink. So, we ended up living in the morning and coming back to rest late at night.
All in all if you want to keep your budget low and the quality of the apartment fare I recommend you to book this apartment. In other words the apartment is really good value for money.

Thank you very much Emilio and Natali for the accommodation! I wish you the best.
