We stayed for 3 days. We have arrived three hours earlier that the check in time but the owner was very helpful and gave us the keys much earlier that expected. Also, to any question we had before our arrival he always replied on the spot. Very friendly and polite.
The flat was very clean and same as the photos, maybe a bit smaller in reality but perfect for a family of five. There was always hot water or heat in the flat whenever it was required.
The neighborhood was fine. Sagrada Familia was 3 minutes walk from the flat, same as the Metro station and the sight-seeing tour bus stop. Also, right across the street was an Aldi shop.
Once again, thank you Oscar and Maria for your hospitality.
