We had a great time staying at Casa Serrano. There were six of us, and we each had our own room -- though we mostly hung out in the living spaces, kitchen, and back yard patio. The location is great -- walking distance shops and restaurants (we were big fans of Cachito right on the corner for quick bites) and within reach of everything else by car/taxi. Max and Rafael were accommodating with our arrival/departure schedule (which changed frequently) and in touch during our entire stay. We will definitely stay again -- hopefully the weather will be more pool appropriate! :)
