We spent a weekend in the apartment in September 2014. Everything was fine so we had a great time. The apartment is like shown on the pictures: clean, well-appointed and quiet. Receiving the keys was not a problem and the contact person (Danni) was nice and helpful.
It takes about 45 mins to get from the airport to the apartment by metro - it´s really easy. The metro station is very near (sometimes you can even hear the metro from the apartment - nothing bad) so it´s easy to get everywhere. A few shops are close to the apartment too.

We recommend the apartment for a trip to Barcelona :)

Thanks!
