Wonderful apartment! The location is in a quiet area- it felt clean and safe. The metro stop is 1 min walk from the apartment, and there are plenty of options for food- grocery stores, cafes, and restaurants. Santutxo is nearby- excellent tapas, sangria, a nice terrace and the service was incredible.
The apartment itself is very clean and has nearly everything one might need. The only thing that would be useful are some fans for the July heat in Spain. Oh, and the large, double shower is amazing! A great way to cool down every night.
Sofia was a very welcoming host, and extremely kind and friendly- she was eager to give us some inside tips on where to go and even explained some parts of the city to us with a map.
If I came back, I would stay there again!
