Fen is a great host! Check-in and out were easy, and she let me store my luggage there on the last day before my flight. The room is clean and comfortable, with a microwave and fridge. There's also a desk to get some work done. Location-wise, it's about a 20-25 min walk to Caltech, 15-20 minutes from Old Town Pasadena, and 5 min from the Filmore metro station, which is perfect for getting to downtown LA. I'd happily stay here again the next time I'm in Pasadena.
