Montauk is one of my favorite towns on Long Island, the other is Greenport on the North fork. We have stayed at many places in Montauk, including Montauk Manor. Its a peaceful setting, castle like and most of the rooms are privately owned. The room sizes vary, from studios to 3 bedroom. You have restaurant on site, food was good, however you have so many options in Montauk once you venture out..Tennis anyone? courts and views. WOW, would suggest bikes. we took our own but rentals are available in town..
MM is really not walking distance to the beach, however they did have shuttle service..you might want to ask when you check in. Montauk is BIG on fishing, deep sea for a day, also SPA treatments at many places including MM. Tons of restaurant choices too, low end:

Bring your sunscreen and good walking shoes/flip flops, Welcome to Montauk, the END. (that's a local popular bumper sticker)
