Some inconveniences but the price is great
Overall, for the monthly rate this place is a good deal. Unfortunately, their access hours only go until 7pm, which can make it difficult to make a trip over on a weekday. The carts and elevators are also smaller than other storage places in the Boston area, which makes the move-in process a bit frustrating if you aren't prepared for it. But if you've got mostly smaller pieces you haven't any real difficulty. (Large furniture can be a pain, though!)
Also, on my particular move-in date, one of the lifts wasn't working and one of the cargo doors wouldn't open. The attendant said this wasn't normal, so I hope it isn't indicative of the general state of maintenance, but I can't give them a higher rating if their equipment wasn't fully functional when I was there.
