Nothing wrong with the hotel itself, but the surroundings were horrendous. I've only got myself to blame for booking a stay right in the midst of the infamous Tenderloin, but still the room reeks of dog pile or marijuana, crazy people shouting in the midnight, police raids and sirens going on seemingly forever, and the safety around is also of great concern.
Again, nothing wrong with the hotel, the staff were great people, the room was tidy and clean (except for the smell). Would have been a perfect stay for a business trip.
