Sandy's home is clean and beautiful - when checking in, knock on the door of the unit BEHIND the house off the street.
She was beyond courteous and her pup Jax was a quiet (hardly barked) bundle of love. My girlfriend and I had more than enough room; there's a walk-in closet and bathroom attached to the room and both the room and bathroom have heaters!
If you are worried about the dogs, they are not allowed upstairs, and you genuinely could not find a dog odor if you tried.
The Fremont area is really convenient - you're within walking distance to paseo, the troll, and a lot of great food. Sandy even has a guide printed out in the room if you didn't want to research.
I would definitely stay here again. Great room, location, host, and conversation.
