Had a great stay during the Rugby World Cup tournament at AT&T Park. We knew Noe Valley was a bit out of the way from where we were going to be spending most of our time, but were happy to explore a part of the city we probably wouldn't have visited otherwise.
It did get a little noisy in the mornings with people walking around and talking right over the guest room. During the week I was woken up around 7am each day, but luckily I'm a pretty heavy sleeper and was able to ignore and fall back asleep. Seems like everyone was out of the house by 8am as all got quiet again around then. There were ear plugs left for us on the night stand, but I didn't need them!
Overall, a great place to stay!
