We thought this place was amazing. Martin met us at the door and made us feel welcome, and even took the time to answer our questions about Barcelona and show us where things were on the map. The flat is beautiful and modern inside, and the kitchen was large and well-equipped enough to cook dinners in. The views of the Sagrada Familia outside are stunning, and the nearest underground station is about a 5 minute walk away, making transit around the city easy. Although the area is bustling, the flat itself was very quiet - unfortunately the neighbors upstairs are quite heavy-footed, which may wake you at night if you're a lighter sleeper. Overall, we had a great experience staying here and I would 100% recommend it.
