Location was perfect! This being my first time in Barcelona, I was impressed that the noise level was low. Theres a few restaurants in the nearby area and the apartment sits right over a restaurant. I couldn't even tell if they were open because I couldn't hear music or people talking. My guess is that they use an acoustic ceiling. The balcony overlooks the restaurant's patio but no one starts getting there until after 6pm so it was private. The apartment was clean but only complain about anything would be the pillows. Overall, super great place to stay. I felt sketchy when being asked for my flight/train number but it makes sense. On that day, my flight was over 2 hours delayed and they have to come in person to give you the keys. Overall, i give this a 5 star rating.
