THE most amazing hotel
We traveled to the Liberty Hotel (formerly the Jail on Charles Street) for a short family vacation July 11-15. The hotel, besides being in a great location, was truly amazing. The staff, from the doorman to the waiter at the restaurant, were fantastic. Friendly and accomodiating (we ended up at the Liberty because we were looking for adjoining rooms and the LIberty was the one hotel out of the 6 we checked to really work to help us out), the Liberty exceeded our expectations. It is located just steps from a great ice cream shop (JP Licks) and really close to the Boston Common. In addition, they gave great advice for a private tour service and restaurant recommendations. 
The rooms are modern and spacious, the restaurant (Clink) serves a great breakfast and the bar (The Alibi) has become the new "it" spot for the up and coming in Boston. 
The best part was that each night there were functions going on in "The Yard", which is the courtyard outside the bar. On the first night we were there, it was a bring-your-dog-to-the -bar night. About 50 people had their dogs and there were bowls of food and water all around for the four legged set. Another night it was a fashion show for local designers. We could see all these things from our room windows, so that was fun for the kids. And don't be worried that the loud music or commotion from The Yard will keep you up--the hotel is very good about turning off the music around 9:30 or 10...and even then, it wasn't affecting our kids' room at all. Suggestion if you go and want complete quiet, request a room that doesn't look onto the Yard. 
All in all, a fantastic place and one that my husband and I want to return to without the kids!
