Excellent hotel, great location
This was our first visit to Boston and we were only able to stay for 2 days, so we wanted to ensure we found somewhere central. The hotel is accessed through a side door at the entrance to a car park, not too difficult to miss but my boyfriend ran ahead to check it was correct as we had our luggage (which we'd just wheeled for 15 mins from the station.) The concierge came out to advise me that, yes this was the hotel and I couldn't help but feel like he was taking the mickey out of us... but never minid! We checked in quickly, with the added touch of being given a glass of champagne whilst doing so!
I had read reviews where people had said the corridors smelt of vomit and unfortunately we found the same thing! However once in the room there was no smell, it was just pretty strange and unpleasant whilst in the corridor.
The room we stayed in was perfect with a lovely bathroom, great toiletries and a huge comfortable bed. Approximately a 5 minute walk from Boston Common, and 10 minute walk from "Cheers" this was a great place to be based. 
When walking to Boston Common from the hotel you encounter the head office for "Old Town Trolly Tours." This was great and very worthwhile. I had done a tour with the same company in Washington D.C and knew this would be worth doing whilst we were in Boston for such a small amount of time. As it's a hop on hop off service we also walked the length of the Freedom Trail as well whilst hopping off and on at our convenience. We didn't have time to do the "free" river cruise that comes with the ticket so I pushed that point and we were given a reduced "trolly only" 24 hour ticket. Worth asking if you're not fussed on the cruise!
All in all, great hotel, would go back tomorrow!
