We were at this location of seven nights and do recommend it to others. This WorldMark hotel is located two blocks north of Union Square and one block away from the gate to Chinatown. There is both Valet parking and self-parking across the street. The ladies at check-in were very helpful and so were the Concierge. We stayed in a one bedroom with a living area. The living area had coffee maker, microwave, mini fridge and dishes. There are many grocery stores along this street where you can pick up food to eat in the room. Our rooms were clean, well decorated and each room had its own ac unit. You do not get housekeeping service unless you stay more than seven days. But if you need clean towels or the trash emptied they come right up when you call them. At this location there are free washers and dryers for the guest to use. We were on the fifth floor of the hotel and although there was lots of traffic on the streets the noise level wasn't too bad, but do bring some earplugs. There is only one elevator in the building so sometimes you have to wait a bit for one to arrive at your floor.
Upon arrival we were asked if we wanted to learn about "time share" that they offer. You do not have to go to their meeting, you can say no. We got asked every time a new sales person was on duty while we were there. We politely told them no, we were a guest of the owner of a time share and went on our way. They weren't pushy, just consistent.
This is a location that I will return to so that I can finish seeing San Francisco.
