The apartment is comfortable with minimalistic decorations, yet cozy. There were all basic necessities to stay as a tourist. The location is great - near bus station from/to airport, close to restaurants/bars, many tourist attractions and beach.
Before reservation I read other reviews that neighbourhood is loud. As the apartment is located in central Barcelona with lots of bars then, yes, at late evenings people hang around. With open windows we could hear them on the street but with closed windows the noise didn’t trouble our sleep. The apartment is on the 5th floor with narrow staircase.
Our host was welcoming, easy to communicate and flexible. They made sure that all our questions were answered and gave us recommendations how to spend time in the city.
