Even in a city known throughout America for the beauty and stability of its buildings, the Karp Building, now the Hotel St. Michel, was a high achievement, both in artistic design and substantial construction. It is three stories in height, of heavy concrete and hollow tile construction throughout. At the time it had modern requirements, this included a sprinkler system, and a brass manual controlled elevator, which still resides in the Hotel St. Michel today.
Originally the first floor held twelve retail shops while the upper floors featured thirty-four offices. Eventually the offices were converted into hotel rooms and the property was named The Hotel Sevilla. In 1979 the building was purchased by Stuart Bornstein and Alan Potamkin and renamed The Hotel Place St Michel. A restaurant was established on the ground floor, first as La Crepe St Michel, subsequently expanding to become the iconic Restaurant St Michel, which ran successfully for thirty five years. The restaurant space is now operated as the internationally acclaimed Zucca Ristorante. Since its purchase in 1979 the entire building has been restored and become a modern world-renowned boutique hotel and historical landmark under the same ownership.
