70 Park Avenue (Formerly Iberostar 70 Park avenue) is now among IHG's (InterContinental Hotels Group) luxury brand hotels. 70 Park Avenue is a 4-Star boutique hotel, located in Mid-town, an area most sought after by tourism and businesses even by NY standards. The exterior of the hotel is a chic building of both legacy and modern brick, built in 1928. The interior which was renovated in 2016, has a sophisticated classic modern feel and provides a refined design in and out. However, due to the hotelโs outdated 2-pipe fan coil AC system, it could not find solutions against the complaints about the AC. Especially during the Spring and Autumn season, customers had varying requests, wanting cooling or heating, but the 2- pipe fan coil system that they had been using could not respond to the demand, which created lack of comfort for our guest and no way to be solved.
