We didn't meet Helena but the communication with her was easy. The doorman let us in and explained everything (he didn't speak English but my wife spoke Spanish so we were able to communicate). The apartment is small but clean, efficient, and perfect for two persons. The elevator is a welcome sight after a long day of walking around Madrid. It is located not only near the three major museums with easy access to bus and metro, but also right on Plaza Jesus where great tapas bars and restaurants are located. Overall, this is a great place to stay and we would stay here again when we come back to Madrid.
