Try the "Belleclaire" on 77th St (Upper West Side), or "West End Studios" in the area too. You could also check out a couple of new hotels in Long Island City in Queens (one stop on the 7 train from Manhattan) I've seen a "La Quinta Inn" and a "Comfort Inn" about a block away from the train stop. Long Island City is an industrial area but you are only one stop (5 minutes) from Grand Central station. I used to live close by and the area isn't that bad. Good luck!
