I stayed at Danni's apartment for three months and loved it. The location is excellent - right in the heart of Fremont with walking access to restaurants, coffee shops, bars, and the Fremont canal park. And the view from the living room/balcony is incredible. The apartment itself is very well stocked with everything you need to cook and stay comfortable. Appliances are pretty new and finishes It has a real homey feel to it, not sterile and basic like a lot of other places. The books and original artwork warm the place up.
Danni herself was helpful and communicative when I had questions, but otherwise left me alone. She was a great host. Not to mention her homemade granola is delightful.
As some other reviewers mentioned there is some street noise on 39th but I got used to it pretty quickly. It also comes and goes with rush hour, so it's pretty mellow on weekends.
I would happily stay at Danni's apartment again.
