We've stayed at the Sheraton often. It's a full service hotel with gym but no spa. It's on 51st and 7th so close enough to the theater district and Times Square without being in the actually hub where it can get very crowded with pedestrians. We use to like the hotel better when it had a big “library” bar that served food and great cocktails but the Sheraton replaced it with the “link cafe” area. There is wi-fi access, a small bar area and a prepackaged small food kiosk area. The hotel does have an onsite breakfast/lunch restaurant as well as a Burger Joint for dinner. The Burger Joint has been many different restaurants so I can’t vouch for the food there.

They have a very nice club level bar if you book in that category it's usually open weekdays only with continental breakfast and appetizers during happy hour.

You are in walking distance to Central Park and Rockefeller Center as well as having public transportation at your finger tips. Rosie O’Grady’s is across the street and gets a nice after-work crowd as well as serves good hearty food. Around the corner is Le Bernandin a Michelin star restaurant and Bobby Flay’s Bar Americain (good food). A short walk is the famous Carnegie Deli and Victor’s Café which is a Cuban restaurant that has been around for years and is also good.

I'd be happy to answer an additional questions you have about the Sheraton.
