I spent just over a week at Carmen's place. It was perfect for my needs, having all the necessary amenities in a clean and tidy space. The kitchenette was also excellent for quick meals. Super easy check in, with everything well communicated and labelled. The place is within walking distance of supermarkets and various bus stops, making it easy to get to Pasadena and Caltech if you don't have a car. Highly recommended!
