It is a clean apartment, what you see in the advertisement is what you get. We had an amazing stay in Barcelona, also thanks to the Oriol and Claudia.
We had contact through whatsapp, which worked perfect for us. If we had a question on things in Barcelona (not even concerning the apartment) we got very helpful information.
So we felt very welcome and found the apartment to be a nice place to explore different parts of the city. The Sagrada Familia was a 10 mins walk max.
