This is one of several options for staying overnight and leaving your car in the hotel parking lot for up to two weeks, a good deal considering the cost of parking near Boston's Logan Airport.
The Adams Inn is good for travelers coming from the South Shore, Cape Cod and the Islands as you don't have to contend with inner city traffic.
The rates are reasonable, the room and bed were clean and comfortable, the complementary breakfast was adequate, the staff friendly and competent.
The downside:
It is difficult to get to with spaghetti roads, construction blockages and poor signage. Even with a GPS we had trouble.
The shuttle to the airport leaves once an hour so you are likely to be too early or too late for your flight, and on the return you could be facing an almost one hour wait to be picked up. We had to wait 40 minutes. It is about a 20-25 minute drive, so if time is more important to you than money, you should stay in one of the other hotels closer to Logan that also have extended parking such as the Courtyard (formerly a Holiday Inn). There are several web sites for these hotels. We used ParkSleepFly.com
