I stayed in this unit for 3 months and had a wonderful experience. The unit is trendy, spacious, clean and QUIET! I never heard any noise in other units. Early on I had some problems with the cable not working, lights that were burnt out, and clogged disposal and a broken dishwasher, but within 24 hours Zeus had responded, organized and resolved the issue (I imagine these were problems from other users that just never reported it because their stay was so short).
The area is about a 10-12 minute walk from Westfield mall, the downtown area, and ATT Park. I felt safe and comfortable in our building at all times (considering there are many parts of the city walking that I did not).
I would definitely 100% recommend this place if you are staying in SF!
