Catalina's place is a excellent modern apartment, that has some amazing views, it's a really convenient location in San Telmo, easy access to the city centre via buses or walking.
The apartment was clean and as described, the aircon especially was a welcome addition for the heat.
Catalina's mother welcomed me on arrival and was good enough to be flexible with check-in time, very friendly and provided me with great tips of places to go and things to do.
Overall a excellent experience, would recommend, thank you both for a great stay!
