Located in Charlestown on the Charles River, the hotel is much larger than Residence Inns we've enjoyed and a step-up at Category 5. In addition to the classic Residence Inn complimentary breakfast, the RI features a Harborwalk Cafe for dining alfresco - perfect for the spring.
Postscript 4/21: Parking, in general, is a huge challenge for thriving urban centers like New York and Boston. Boston handles the challenge very differently from New York by establishing a quota of street parking that favors city residents who in fact make up their tax base.
Thumbs-up for the RI Tudor Wharf. The valet do an outstanding job meeting the challenge to ensure that guests staying on-property have in/out parking privileges. There is also the option to self-park overnight with a vendor that services visitors to the USS Constitution nearby.
Since I cannot specifically request a suite using marriott points, I was limited to the Springhill or Townplace suites or the Courtyard Cambridge where I was able to speak to someone to guarantee a suite for the points.
I do not think the Residence Inn option would have been available using points.
Using 25,000 points you can reserve a 1 bedroom queen suite w/queen sofabed, a harbor view and complimentary breakfast for the entire party at the RI Tudor Wharf. There is excellent availability. As graduation time approaches in May, it will be more difficult for obvious reasons. If you require more privacy, request a complimentary upgrade to 2 bedrooms as a Platinum overide provided there is a 48 hour window prior to arrival. The RI is located in the upper right hand corner of the map shown below in Charlestown right across the bridge. From the Residence Inn, the hub of downtown Boston is literally steps away.
