Great place to stay, extremely well located especially if you are into the nightlife. All of the best restaurants in List seem to be around the corner and the neighborhood people are very friendly.
Our host Miguel was very hospitable and helpful.
One note, we stayed on weekdays and the bar downstairs closes around 3am. The double glazed windows mute most if not all of the sound but if you are a particularly light sleeper then reconsider. Otherwise there are two fans in the apartment which are more than adequate in summers
