We booked two rooms at the Belleclaire, one for myself, my husband(we got married while there), son(14months, no bath which for his age wasn't good) and my mother, another for my brother and sister in law.
Both rooms were great, clean, well equipped.
Travel cot supplied which was wonderful!
Our two down sides to this hotel were the heating(noisey & you have no control over it) and the outside noise(yes I know NYC is like that but I've been before but this was unreal) the windows are old and hold out nothing!
Staff were lovely, lobby was beautiful, and the hotel couldn't have been in a better location :-) More
