This hotel/hostel is Ok for a night or two but i wouldn't stay here on longer stays. The hotel is newly renovated and well located but it's quite bare/simple and doesn't offer much in terms of comfort and privacy. Noise travels easy through the walls, the radiator makes weird and loud noises during the night and there's no AC (although SF is. It necessarily super hot, it does feels a bit stuffy inside the room). That said, the room is neat & clean and if you're here on a very short stay, it's totally recommendable!
On a side note, one of the front desk employees were EXTREMELY rude (he has a accent, I bealive he's French) - he had a melt down because I rang the bell (when I could not figure out how to use my fob to open the front door) at 5:30 pm. Seriously???? He was sitting just across the hall and was out of his mind that I buzzed the bell and he had to push the button to open the door for me (plus other guests). Everybody else we're friendly and polite!
