Not up to modern standards
Stayed two nights for a conference also in the hotel. The location is great, right downtown and across from the Alamo, and it's easy to walk to anywhere along the river, etc.
The service was slow--while standing in line at the check-in counter, we had to resort to calling the hotel just to get someone to the desk. The building itself is historically interesting but rather substandard and smells awful in the conference rooms. The room and especially bathroom were not worthy of the price.
This place has its charms, especially the bar with its fantastic woodwork and friendly staff. But it's not a luxury hotel by any stretch, and has other issues that you wouldn't see in even average hotels.
