The Ansonborough is a beautiful hotel with great staff and service. Our room on the first floor was very large with what looked like a 16-foot ceiling. The style is like warehouse-modern. Unlike some other customers, we really enjoyed ordering breakfast (complimentary and paid-for items) through their web-based "scan QR code" site.
Now, after having read another review about a "sewage" smell before we went, I can now confirm that there is a slight sewage smell in our first floor room. However, this is not the fault of the hotel but, rather, an issue with some sewer sidewalk caps outside on Hasell street. Perhaps Charleston dept of public works can fix that. Also, some thin walls. I strongly dislike hearing people right outside on the sidewalk chatting for an hour at 11pm as well as hearing a neighboring room playing loud music albeit prior to 9pm. Other than that, great hotel. Get a room on 2nd floor or higher.
