Oscar and Vanessa (and Barbara, on arrival) were extremely helpful and attentive from the time we booked their flat to when we asked for restaurant suggestions to when we needed quick advice on where to buy some fresh shrimp. Their place is in a terrific neighborhood, on a mostly quiet and very pleasant street, and the apartment itself is perfect (comfortable bed, first-rate shower) and well-equipped (French press and Moka pot). We were in Madrid for almost a week--we'd repeat at this apartment without hesitation.
