I stayed for a month and found it clean and mostly comfortable. I was there for work, so I spent more time in the unit than most people who are just using it as a landing pad while visiting the area. That definitely skews my review.
It was well-located in relation to Old Pasadena and the Huntington Library and the guide to the city that Carmen and Dustin provided was very useful! They are super friendly hosts.
I cooked a lot there and the kitchen had everything I needed and was well-organized.
The bedroom was very comfortable and I slept well in the bed, but I did find the wifi a bit unreliable and the old pipes let in some fumes. If it hadn't been such a hot time of year, keeping the windows open would have solved that problem.
