My husband and I stayed there on Columbus day weekend. The room was a nice size and had a mini fridge. Hotel was quiet with several quaint courtyards. Staff was helpful and the breakfast was very good. The only draw back was that it was a few miles from town, but they do have a shuttle that runs every hour.

We stayed here in September for an overnight stay. We did not know what to expect since this Inn is out of town near the airport. It was just fine! Comfortable beds, room was clean if not a bit dated. We did not want to stay for more than one night on the island as we were there to attend a party on Saturday night. Most places require a 3 night minimum in season.
We got a good rate online that came without breakfast.
We had breakfast there on Sunday and it was a good but not exceptional breakfast. Large buffet that would satisfy most people's needs.
The help were all friendly and the bus service was just fine. We used the bus three times during our brief stay and it was prompt and the drivers were friendly. We would stay there again since we do not like to pay the high rates of the inns downtown and the location turned out to be no problem at all.

Stayed here 3 nights in September (post-Labor Day) for a continuing ed. conference. Staff was friendly and helpful. The Inn was quiet, had a few of the usual amenities, and our room was spacious, clean and more than adequate-- Nothing at all fancy, but good, solid, motel/ hotel type accomodations. Van pickup from the ferry was smooth and shuttles to town ran at least hourly (and twice an hour in the evenings) and were very reliable. If we were on the island again, and not at an on-site conference, I'd look into somewhere with a little more "mojo" but, especially if traveling with kids, I'd think the Inn a good choice, largely on account of having a pool, complimentary breakfast buffet, a little bit of isolation and a good dollar value on the island.

My wife and I have been to Nantucket as a couple about 5 times in the last dozen or so years -- and have stayed in cute/quaint, somewhat pricey B&Bs near downtown proper and had wrongly thought that staying out near the airport would be a logistical/geographic burden. However -- it was not and it actually had its benefits as it turned out.

Keep in mind the shuttles (to/from beach/town/ferry) are frequent and useful. Should you take an extra few minutes to plan your day -- you should have no troubles.

We had a driver escort us, our luggage (including 5 bikes) for free to and from the ferry with a smiles/good humor. [PLEASE be generous with tips -- these folks work hard (and often in traffic/heat.)]

We took our three children (ages 9, 9, & 6) and one of their friends (7) and stayed in a less-than big enough 'cottage' (king, one bed) room for three nights -- and we used the extra floor space to place a couple air mattresses down at sleep time -- and they loved it. ...which made it both affordable and comfortable. We took the air out in the AM -- and packed them away -- so we had plenty of room all day.

The pools (in and out) are great and clean.

The staff is mostly attentive and friendly.

In truth the facility is a little dated -- but they maintain it pretty well and management have not been so foolish as to throw good money at bad by making it into something it is not/or can't be. It is a GREAT (and practical) destination for family -- especially given the two pools and attentive staff.

...again the grounds were/are clean and more-than adequate.

Bartender was especially friendly -- although we had few 'professional' dealings with him given it was a 'kid' vacation.

As stated we brought our bikes -- and that made it particularly nice given the bike paths all about (to town/to beaches/entire island). We had to rent an additional child's bike with helmet for $18+ that was delivered to the hotel lobby and they picked it back up the next day.

Having nice weather always helps -- and we had that.

If you have children (or don't) save yourself the $100 to $200+ per night and stay at the Nantucket Inn. Use the extra dough you'll save for a nice lunch/dinners, harbor cruise, bike rentals, etc...
