You will hear your neighbors if they raise their voice. Comfy bed. Breakfast was so-so. No air conditioning but the ceiling fan makes up for it not sure for the summers. Staff was very polite and accommodating. Good area near transportation and shopping areas. Overall, i liked my stay

Disliked: Room comfort

Disappointing. Better is Available Close By

Drafty. Crappy baseboard heat. 100-ish year old building. Cold even with thermostats up to max. Narrow hallways, 7 foot hallway ceilings, fire exits not clearly marked out. One of two TVs quit getting cable signal first day. Worst of all is the false advertising. A week AFTER making the reservation for a room advertised as WITH INCLUDED BREAKFAST....we got an email saying they would be charging us an extra $20 PER NIGHT "amenity fee"--primarily for the supposedly included 'breakfast': a few pastries and bagels, a few pieces of fruit, tiny yoghurt cups and instant oatmeal packets. Not even a microwave. I've stayed at Budget Inns with more and better "amenities'--and they didnt charge extra for theirs. Not recommended, considering what they charge. You can do much better in the area.
