Quirky Hotel, Fine for a...

Liked: Front desk staff were friendly, and the location was very convenient. Just a short walk from Boston Common and close to a wide array of restaurants and shopping. Room was small but comfortable. Strangely had a DVD and VHS player (who brings VHS tapes on their vacation?!). Good for a short stay. Choose it for the location and price, not amenities.
Disliked: Guests are told breakfast will be available at 730, but it was closer to 815 (which is fine, but they should just say it's later rather than telling people 730). Staff member directed patrons to the restaurant instead of telling them to wait a few more minutes for the pastries. No coffee or hot water making facilities available outside of breakfast. Decent soundproofing but central air makes a loud rattling noise. Room was advertised as having a mini-fridge, but it did not. Very little storage space in the room if you have a suitcase. Sometimes the guest "lounge" (really just the restaurant's private event space) is used for private events and can be extremely noisy for adjacent rooms.

Overall great.

Liked: House keeping everyday
Disliked: Noise from another room

Very good

Location, location, location

Liked: Charlesmark Hotel is in a great position on Boylston Street opposite Boston Public Library and close to Copley T station so is ideal for getting round Boston. Rooms were fine and about the size we thought they were going to be. Reception staff were friendly and helpful. Lift to all floors and keys allow room access and also front door access as front door is locked after 10pm.
Disliked: The hotel advertises the fact you can get coffee and pastries from the cafe attached to the hotel but in our experience this was very hit and miss, most mornings the pastries had not been delivered. I think if you advertise a service then you should provide, likewise the room servicing seemed odd as sometimes the bed was made and sometimes not but towels were changed out, it was like half the room was serviced. To me for the hotel price then tea / coffee making facilities in room could be provided.
