We liked our staying in Andreu's apartment. The location is perfect, just about 4 minutes walk from a metro station, and there are various supermarkets nearby. The Sants railway station is within about 10-15 minutes walk. The apartment has a splendid view from the panaramic window and is really well equiped. There is anything you may require for a comfortable stay, including a washing machine, a dishwasher and even salt, sugar, spices, olive oil etc.
Andreu is a perfect host. He welcomed us at the apartment and gave some helpful advice. During the stay the communication was also good.
We highly recommend this apartment for a perfect holiday in Barcelona.
