Na’s place is great. My parents stayed here a week. The unit is private and quiet. Other reviews mentioned noise from the house above. However apart from the dog barking sometimes my parents were not disturbed by any other noise. The amenities were great - fast internet and good heating. Of course, there is no kitchen; so any longer stays may be difficult.
Na and Ivan were very responsive even over the holidays.
The only small downside is that the parking spot that is indicated is not always available. I found other cars parked there a few times over the week stay.
All in all a good value in the Bay Area.
