The place is clean and comfortable, the neighborhood is quiet and friendly, and you can visit the nearest laundry/restaurant/barbershop/pub/grocery at Colorado Blvd within 5mins walk. I stayed for a month during my research visit in Caltech and it's only 15mins walk. The owner also message you every once in a while to make sure that your stay is nice and comfortable as possible. A great value place for a stay in Pasadena!
