I had a lovely time staying in Cathryns home. The whole house was clean and tidy and it was handy to be able to use the kitchen and keep stuff in the fridge. The bed was comfy and having an ensuite was great.
Potrero Hill itself was a nice safe area that i felt comfortable walking around on my own any time of day and although its not central i easily got the bus in and out of town each day.
Cathryn is a brilliant host. Very welcoming and friendly and has great suggestions of things to do and see if you get stuck!
