Alex was very punctual and kind to my friend during check-in (I arrived later). He also made the check-out process incredibly easy. The location is great and you can easily access many parts of the city by foot.
The only negative would be the lack of an AC unit and nets for the windows. It was very hot in June and we had to decide between the heat with the windows closed or the night air with bug bites the next morning.
Overall it was a good trip and would recommend his place during the cooler months.
