This place is located in a great spot, feels very secure and I could stay here for a week or longer if needed. I have no concerns about the actual unit or even the entire floor the unit is on.
That said...the reviews that mention the odor of cigars are valid. The reviews that mention a slow elevator are valid. The reviews that mention a cumbersome check in process initially are valid.
I decided to take the stairs often which helped with the elevator issue and since smoking has been done on the second floor of this building for 165 years its not likely that there is a solution. Rest assured though that the floor your room is on and your room have no odors at all, its purely in the lobby and elevator and other common spaces.
Great Internet, nice amenities, etc. Could definitely relax well here.
