Catherine's place is a really nice one. It is a big room and very clean. I think it could be a little dark and, as it is intended to function also as a work place, sometimes it was difficult for me to have a bright place to do that. It has two closets but you can use only one of them and that's the only place where you can put your clothes and bags. Maybe it needs more furniture with drawers to store clothes, because sometimes it was uncomfortable to put all your things in the closet. Another thing that it is important to keep in mind is that at 4 or 5 am you could hear a noise coming from the corridor that I think was associated with the extractor or something. So, if you don't have heavy sleep it will definitely wake you up, as was my case. Also, sometimes I found that my bathroom's door was open, even when I left it close and I still don't know who did that and why. It is also important that, if you are a long term guest, you are expected to clean your room and bathroom, because nobody cleans the room or takes out your garbage while you are staying there. For the laundry, you have a washing machine and dryer in the ground floor. But specially for the foreign guests, you need to have quarter coins, this means that you can't use any kind of coin and sometimes it is difficult to collect several coins of that type. In terms of location, it is really good. You are at 30 minutes walk from Caltech, you also have some grocery stores nearby and you can also walk to Old Pasadena. Communication with Catherine was really good. She always answered my questions and was very helpful when I needed to leave my bags for an extra time after we checked out. Overall, a good place to stay.
