The location is perfect for visitors who want to travel in Pasadena. It's less than 20-minute walk to all the restaurants and supermarkets nearby and also Norton Simon museum and the City Hall.
Check-in is easy. The instructions are clear. The door locker was broken once, but the host responded to me in a few minutes and solved the problem.
In terms of the room, it's kind of like a hotel where you mostly stay in your own room though you can also hang out in the public spaces. Most of the time it's really quiet, especially at night, while occasionally you can hear others chatting or making phone calls.
The restroom is across the aisle from the room. The bathtub is a bit old and the water pressure in the shower is not especially high. But it's fair enough to use in just a few days of stay.
Overall, nice and worth the price.
