Great value in a fantastic location! Highly recommended, especially in the gorgeous neighborhood of Beacon Hill. The kitchen had a good selection of utensils and supplies (pot, pan, etc) but I would bring a can opener, oil, spices, etc (they do not advertise having such things).
As for room for improvement, our main concern was the keyless lock not working when we arrived late, but after reaching out to the overnight maintenance guy he drove out to let us in, but our original code was not fixed so we used the staff code he gave us. Not a big problem so long as we had a way in.
Again, highly recommended given how central it was and how reasonable the price was. Just a tip: the walls are pretty thin so be courteous to your neighbors. You might be louder than you realize.
