I stayed @ Paola's place for 2 nights.
She has thoughtfully provided a comfortable space for at least 2 adults but I think if she allows babies or small children you could have 4 people.
The space is very clean, organized, comfortable . Nicely decorated.
Easy parking on street.
I think it wouldn't be much of a walk to access bus and some restaurants nearby, but easier with vehicle for me.
There's a microwave in studio.
Very welcoming space and if I'm back in Portland, will definitely stay again!
