We had a great stay in this apartment.
The host was very welcoming.
Everything is as described on Airbnb - the apartment is clean, very comfortable and has many amenities.
This is a perfect apartment for a city break in Barcelona. You can see the Sagrada Familia from the bathroom and you are only 5 minutes walk away. The Sagrada Familia metro is a 2 minute walk away and is well connected with the city. And what a great city!
