Area is top (7-10 mins walk to Union Square), calm and quiet neighborhood. Food & Beverage store just across the street. Room ist very clean & comfortable. Bed size enough for 2 people. Mary is very helpful and answers to messages within minutes. I strongly recommend this accomodation! Great experience. Thank you, Mary.
If you want to save money and enjoy the city in a calmer way then avoid SFO when Salesforce.com is having its annual conference (more than 20k people in town).
