Overall, we really enjoyed our stay in this apartment. With the sagrada familia down the street, it has an amazing location. The host was super accommodating with an early check in, which was very helpful.
We were only disappointed in the lack of accommodation for 4 people. It only had three bathroom towels and no hand towels. It also did not have a big enough sheet for the futon. The sheet was 100% necessary as there were many stains all over it. We arrived and it was flipped around and covered with a blanket to hide this. On top of that, there were only 3 bed pillows and one of the pillows had gross stains, so basically we had no pillows for the people who slept on the futon.
Alongside the lack of accommodation for 4 people, it is important to note in your description that you will hear your neighbors as if they are in the apartment. Also, the neighbors' cigarette smoke fills the apartment when the windows are open.
