Good Location - a few niggles
We recently spent 5 night at the Ames. The location very central you can walk everywhere and the old state capitol can be seen from some of the rooms, as others have said the complimentary breakfast was really nice. The staff on the door were very helpful and friendly.
The few negatives to point out, housekeeping was not consistent, there were days when towels and tolitries were not replaced. Others have mentioned the wifi, travelling from the UK we had planned to use the business centre to book excursions and check in for flights online, we were quite shocked to find that there was a charge to use the internet, we have travelled a lot in the USA and this is the only time we have had to pay for this.
The mini bar again as mentioned everything was expensive. 
Our overall feeling was that the hotel was more into making money, (even the laundry bag could be bought for $35) than customer service. There was not a general friendly feeling from staff. 
Boston is a fantastic city and we did not do everything we planned and will return at some point, unfortunately we would not choose to stay at the Ames again as it did not meet our needs.
