We stayed 4 days at the apt. Every detail for check in was laid out for us. We arrived late and it was still easy to get checked in. The apt is huge, and we had 6 people with plenty of space. The bathrooms are nice and clean. The kitchen was stocked. They provided many recommendations for things to do and see. It was a short walk to Sagrada Família and the Sant Pau hospital museum. Metro station is nearby. It was a perfect place to stay in Barcelona - I will recommend it to our friends. At the end Frédéric even setup our transport to the airport- great place and a great host.
